CPack Archive Generator
-----------------------
CPack generator for packaging files into an archive, which can have
any of the following formats:
- 7Z - 7zip - (``.7z``)
- TBZ2 (``.tar.bz2``)
- TGZ (``.tar.gz``)
- TXZ (``.tar.xz``)
- TZ (``.tar.Z``)
- TZST (``.tar.zst``)
- ZIP (``.zip``)
.. versionadded:: 3.1
7Z and TXZ formats support.
.. versionadded:: 3.16
TZST format support.
When this generator is called from ``CPackSourceConfig.cmake`` (or through
the ``package_source`` target), then the generated archive will contain all
files in the project directory, except those specified in
:variable:`CPACK_SOURCE_IGNORE_FILES`. The following is one example of
packaging all source files of a project:
.. code-block:: cmake
set(CPACK_SOURCE_GENERATOR "TGZ")
set(CPACK_SOURCE_IGNORE_FILES
\\.git/
build/
".*~$"
)
set(CPACK_VERBATIM_VARIABLES YES)
include(CPack)
When this generator is called from ``CPackConfig.cmake`` (or through the
``package`` target), then the generated archive will contain all files
that have been installed via CMake's :command:`install` command (and the
deprecated commands :command:`install_files`, :command:`install_programs`,
and :command:`install_targets`).
Variables specific to CPack Archive generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. variable:: CPACK_ARCHIVE_FILE_NAME
CPACK_ARCHIVE_<component>_FILE_NAME
Package file name without extension.
:Default: The default is ``<CPACK_PACKAGE_FILE_NAME>[-<component>]``, with spaces
replaced by '-'.
The extension is determined from the archive format (see list above) and
automatically appended to the file name. Note that ``<component>`` is all
uppercase in the variable name.
.. versionadded:: 3.9
Per-component :variable:`!CPACK_ARCHIVE_<component>_FILE_NAME` variables.
.. variable:: CPACK_ARCHIVE_FILE_EXTENSION
.. versionadded:: 3.25
Package file extension.
:Default: Default values are given in the list above.
.. variable:: CPACK_ARCHIVE_COMPONENT_INSTALL
Enable component packaging.
:Default: ``OFF``
If enabled (``ON``) multiple packages are generated. By default a single package
containing files of all components is generated.
Variables used by CPack Archive generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
These variables are used by the Archive generator, but are also available to
CPack generators which are essentially archives at their core. These include:
- :cpack_gen:`CPack Cygwin Generator`
- :cpack_gen:`CPack FreeBSD Generator`
.. variable:: CPACK_ARCHIVE_THREADS
The number of threads to use when performing the compression.
.. versionadded:: 3.18
:Default: ``1``
If set to ``0``, the number of available cores on the machine will be used instead.
The default is ``1`` which limits compression to a single thread. Note that
not all compression modes support threading in all environments. Currently,
only the XZ compression may support it.
See also the :variable:`CPACK_THREADS` variable.
.. versionadded:: 3.21
Official CMake binaries available on ``cmake.org`` now ship
with a ``liblzma`` that supports parallel compression.
Older versions did not.

CPack Bundle Generator
----------------------
CPack Bundle generator (macOS) specific options
Variables specific to CPack Bundle generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
Installers built on macOS using the Bundle generator use the
aforementioned DragNDrop (``CPACK_DMG_xxx``) variables, plus the following
Bundle-specific parameters (``CPACK_BUNDLE_xxx``).
.. variable:: CPACK_BUNDLE_NAME
The name of the generated bundle. This appears in the macOS Finder as the
bundle name. Required.
.. variable:: CPACK_BUNDLE_PLIST
Path to an macOS Property List (``.plist``) file that will be used
for the generated bundle. This
assumes that the caller has generated or specified their own ``Info.plist``
file. Required.
.. variable:: CPACK_BUNDLE_ICON
Path to an macOS icon file that will be used as the icon for the generated
bundle. This is the icon that appears in the macOS Finder for the bundle, and
in the macOS dock when the bundle is opened. Required.
.. variable:: CPACK_BUNDLE_STARTUP_COMMAND
Path to a startup script. This is a path to an executable or script that
will be run whenever an end-user double-clicks the generated bundle in the
macOS Finder. Optional.
.. variable:: CPACK_BUNDLE_APPLE_CERT_APP
.. versionadded:: 3.2
The name of your Apple supplied code signing certificate for the application.
The name usually takes the form ``Developer ID Application: [Name]`` or
``3rd Party Mac Developer Application: [Name]``. If this variable is not set
the application will not be signed.
.. variable:: CPACK_BUNDLE_APPLE_ENTITLEMENTS
.. versionadded:: 3.2
The name of the Property List (``.plist``) file that contains your Apple
entitlements for sandboxing your application. This file is required
for submission to the macOS App Store.
.. variable:: CPACK_BUNDLE_APPLE_CODESIGN_FILES
.. versionadded:: 3.2
A list of additional files that you wish to be signed. You do not need to
list the main application folder, or the main executable. You should
list any frameworks and plugins that are included in your app bundle.
.. variable:: CPACK_BUNDLE_APPLE_CODESIGN_PARAMETER
.. versionadded:: 3.3
Additional parameter that will passed to ``codesign``.
Default value: ``--deep -f``
.. variable:: CPACK_COMMAND_CODESIGN
.. versionadded:: 3.2
Path to the ``codesign(1)`` command used to sign applications with an
Apple cert. This variable can be used to override the automatically
detected command (or specify its location if the auto-detection fails
to find it).

CPack DEB Generator
-------------------
The built in (binary) CPack DEB generator (Unix only)
Variables specific to CPack Debian (DEB) generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The CPack DEB generator may be used to create DEB package using :module:`CPack`.
The CPack DEB generator is a :module:`CPack` generator thus it uses the
:variable:`!CPACK_XXX` variables used by :module:`CPack`.
The CPack DEB generator should work on any Linux host but it will produce
better deb package when Debian specific tools ``dpkg-xxx`` are usable on
the build system.
The CPack DEB generator has specific features which are controlled by the
specifics :variable:`!CPACK_DEBIAN_XXX` variables.
:variable:`!CPACK_DEBIAN_<COMPONENT>_XXXX` variables may be used in order to have
**component** specific values. Note however that ``<COMPONENT>`` refers to
the **grouping name** written in upper case. It may be either a component name
or a component GROUP name.
Here are some CPack DEB generator wiki resources that are here for historic
reasons and are no longer maintained but may still prove useful:
- https://gitlab.kitware.com/cmake/community/-/wikis/doc/cpack/Configuration
- https://gitlab.kitware.com/cmake/community/-/wikis/doc/cpack/PackageGenerators#deb-unix-only
List of CPack DEB generator specific variables:
.. variable:: CPACK_DEB_COMPONENT_INSTALL
Enable component packaging for CPackDEB
:Mandatory: No
:Default: ``OFF``
If enabled (``ON``) multiple packages are generated. By default a single package
containing files of all components is generated.
.. variable:: CPACK_DEBIAN_PACKAGE_NAME
CPACK_DEBIAN_<COMPONENT>_PACKAGE_NAME
Set Package control field (variable is automatically transformed to lower
case).
:Mandatory: Yes
:Default:
- :variable:`CPACK_PACKAGE_NAME` for non-component based
installations
- :variable:`CPACK_DEBIAN_PACKAGE_NAME` suffixed with ``-<COMPONENT>``
for component-based installations.
.. versionadded:: 3.5
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_NAME` variables.
See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-source
.. variable:: CPACK_DEBIAN_FILE_NAME
CPACK_DEBIAN_<COMPONENT>_FILE_NAME
.. versionadded:: 3.6
Package file name.
:Mandatory: Yes
:Default: ``<CPACK_PACKAGE_FILE_NAME>[-<component>].deb``
This may be set to ``DEB-DEFAULT`` to allow the CPack DEB generator to generate
package file name by itself in deb format::
<PackageName>_<VersionNumber>-<DebianRevisionNumber>_<DebianArchitecture>.deb
Alternatively provided package file name must end
with either ``.deb`` or ``.ipk`` suffix.
.. versionadded:: 3.10
``.ipk`` suffix used by OPKG packaging system.
.. note::
Preferred setting of this variable is ``DEB-DEFAULT`` but for backward
compatibility with the CPack DEB generator in CMake prior to version 3.6 this
feature is disabled by default.
.. note::
By using non default filenames duplicate names may occur. Duplicate files
get overwritten and it is up to the packager to set the variables in a
manner that will prevent such errors.
.. variable:: CPACK_DEBIAN_PACKAGE_EPOCH
.. versionadded:: 3.10
The Debian package epoch
:Mandatory: No
:Default: None
Optional number that should be incremented when changing versioning schemas
or fixing mistakes in the version numbers of older packages.
.. variable:: CPACK_DEBIAN_PACKAGE_VERSION
The Debian package version
:Mandatory: Yes
:Default: :variable:`CPACK_PACKAGE_VERSION`
This variable may contain only alphanumerics (A-Za-z0-9) and the characters
. + - ~ (full stop, plus, hyphen, tilde) and should start with a digit. If
:variable:`CPACK_DEBIAN_PACKAGE_RELEASE` is not set then hyphens are not
allowed.
.. note::
For backward compatibility with CMake 3.9 and lower a failed test of this
variable's content is not a hard error when both
:variable:`CPACK_DEBIAN_PACKAGE_RELEASE` and
:variable:`CPACK_DEBIAN_PACKAGE_EPOCH` variables are not set. An author
warning is reported instead.
.. variable:: CPACK_DEBIAN_PACKAGE_RELEASE
.. versionadded:: 3.6
The Debian package release - Debian revision number.
:Mandatory: No
:Default: None
This is the numbering of the DEB package itself, i.e. the version of the
packaging and not the version of the content (see
:variable:`CPACK_DEBIAN_PACKAGE_VERSION`). One may change the default value
if the previous packaging was buggy and/or you want to put here a fancy Linux
distro specific numbering.
.. variable:: CPACK_DEBIAN_PACKAGE_ARCHITECTURE
CPACK_DEBIAN_<COMPONENT>_PACKAGE_ARCHITECTURE
The Debian package architecture
:Mandatory: Yes
:Default: Output of ``dpkg --print-architecture`` (or ``i386``
if ``dpkg`` is not found)
.. versionadded:: 3.6
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_ARCHITECTURE` variables.
.. variable:: CPACK_DEBIAN_PACKAGE_DEPENDS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS
Sets the Debian dependencies of this package.
:Mandatory: No
:Default:
- An empty string for non-component based installations
- :variable:`CPACK_DEBIAN_PACKAGE_DEPENDS` for component-based
installations.
.. versionadded:: 3.3
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS` variables.
.. note::
If :variable:`CPACK_DEBIAN_PACKAGE_SHLIBDEPS` or
more specifically :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS`
is set for this component, the discovered dependencies will be appended
to :variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS` instead of
:variable:`CPACK_DEBIAN_PACKAGE_DEPENDS`. If
:variable:`CPACK_DEBIAN_<COMPONENT>_PACKAGE_DEPENDS` is an empty string,
only the automatically discovered dependencies will be set for this
component.
Example:
.. code-block:: cmake
set(CPACK_DEBIAN_PACKAGE_DEPENDS "libc6 (>= 2.3.1-6), libc6 (< 2.4)")
.. variable:: CPACK_DEBIAN_ENABLE_COMPONENT_DEPENDS
.. versionadded:: 3.6
Sets inter-component dependencies if listed with
:variable:`CPACK_COMPONENT_<compName>_DEPENDS` variables.

based installers only) if set, or :variable:`CPACK_PACKAGE_DESCRIPTION` if set, or
- content of the file specified in :variable:`CPACK_PACKAGE_DESCRIPTION_FILE` if set
If after that description is not set, :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY` going to be
used if set. Otherwise, :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY` will be added as the first
line of description as defined in `Debian Policy Manual`_.
.. versionadded:: 3.3
Per-component :variable:`!CPACK_COMPONENT_<compName>_DESCRIPTION` variables.
.. versionadded:: 3.16
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_DESCRIPTION` variables.

Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_SECTION` variables.
See https://www.debian.org/doc/debian-policy/ch-archive.html#s-subsections
.. variable:: CPACK_DEBIAN_ARCHIVE_TYPE
.. versionadded:: 3.7
.. deprecated:: 3.14
The archive format used for creating the Debian package.
:Mandatory: Yes
:Default: ``gnutar``
Possible value is: ``gnutar``
.. note::
This variable previously defaulted to the ``paxr`` value, but ``dpkg``
has never supported that tar format. For backwards compatibility the
``paxr`` value will be mapped to ``gnutar`` and a deprecation message
will be emitted.
.. variable:: CPACK_DEBIAN_COMPRESSION_TYPE
.. versionadded:: 3.1
The compression used for creating the Debian package.
:Mandatory: Yes
:Default: ``gzip``
Possible values are:
``lzma``
LempelZivMarkov chain algorithm
``xz``
XZ Utils compression
``bzip2``
bzip2 BurrowsWheeler algorithm
``gzip``
GNU Gzip compression
``zstd``
.. versionadded:: 3.22
Zstandard compression
.. variable:: CPACK_DEBIAN_PACKAGE_PRIORITY
CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY
Set Priority control field e.g. required, important, standard, optional,
extra
:Mandatory: Yes
:Default: ``optional``

Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_PRIORITY` variables.
See https://www.debian.org/doc/debian-policy/ch-archive.html#s-priorities
.. variable:: CPACK_DEBIAN_PACKAGE_HOMEPAGE
The URL of the web site for this package, preferably (when applicable) the
site from which the original source can be obtained and any additional
upstream documentation or information may be found.
:Mandatory: No
:Default: :variable:`CMAKE_PROJECT_HOMEPAGE_URL`
.. versionadded:: 3.12
The :variable:`!CMAKE_PROJECT_HOMEPAGE_URL` variable.
.. note::
The content of this field is a simple URL without any surrounding
characters such as <>.
.. variable:: CPACK_DEBIAN_PACKAGE_SHLIBDEPS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS
May be set to ON in order to use ``dpkg-shlibdeps`` to generate
better package dependency list.
:Mandatory: No
:Default:
- :variable:`CPACK_DEBIAN_PACKAGE_SHLIBDEPS` if set or
- ``OFF``
.. note::
You may need set :variable:`CMAKE_INSTALL_RPATH` to an appropriate value
if you use this feature, because if you don't ``dpkg-shlibdeps``
may fail to find your own shared libs.
See https://gitlab.kitware.com/cmake/community/-/wikis/doc/cmake/RPATH-handling
.. note::
You can also set :variable:`CPACK_DEBIAN_PACKAGE_SHLIBDEPS_PRIVATE_DIRS`
to an appropriate value if you use this feature, in order to please
``dpkg-shlibdeps``. However, you should only do this for private
shared libraries that could not get resolved otherwise.
.. versionadded:: 3.3
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_SHLIBDEPS` variables.
.. versionadded:: 3.6
Correct handling of ``$ORIGIN`` in :variable:`CMAKE_INSTALL_RPATH`.
.. variable:: CPACK_DEBIAN_PACKAGE_SHLIBDEPS_PRIVATE_DIRS
.. versionadded:: 3.20
May be set to a list of directories that will be given to ``dpkg-shlibdeps``
via its ``-l`` option. These will be searched by ``dpkg-shlibdeps`` in order
to find private shared library dependencies.
:Mandatory: No
:Default: None
.. note::
You should prefer to set :variable:`CMAKE_INSTALL_RPATH` to an appropriate
value if you use ``dpkg-shlibdeps``. The current option is really only
needed for private shared library dependencies.
.. variable:: CPACK_DEBIAN_PACKAGE_DEBUG
May be set when invoking cpack in order to trace debug information
during the CPack DEB generator run.
:Mandatory: No
:Default: None
.. variable:: CPACK_DEBIAN_PACKAGE_PREDEPENDS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS
Sets the `Pre-Depends` field of the Debian package.
Like :variable:`Depends <CPACK_DEBIAN_PACKAGE_DEPENDS>`, except that it
also forces ``dpkg`` to complete installation of the packages named
before even starting the installation of the package which declares the
pre-dependency.
:Mandatory: No
:Default:
- An empty string for non-component based installations
- :variable:`CPACK_DEBIAN_PACKAGE_PREDEPENDS` for component-based
installations.
.. versionadded:: 3.4
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_PREDEPENDS` variables.
See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
.. variable:: CPACK_DEBIAN_PACKAGE_ENHANCES
CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES
Sets the ``Enhances`` field of the Debian package.
Similar to :variable:`Suggests <CPACK_DEBIAN_PACKAGE_SUGGESTS>` but works
in the opposite direction: declares that a package can enhance the
functionality of another package.
:Mandatory: No
:Default:
- An empty string for non-component based installations
- :variable:`CPACK_DEBIAN_PACKAGE_ENHANCES` for component-based
installations.
.. versionadded:: 3.4
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_ENHANCES` variables.
See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
.. variable:: CPACK_DEBIAN_PACKAGE_BREAKS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS
Sets the ``Breaks`` field of the Debian package.
When a binary package (P) declares that it breaks other packages (B),
``dpkg`` will not allow the package (P) which declares ``Breaks`` be
**unpacked** unless the packages that will be broken (B) are deconfigured
first.
As long as the package (P) is configured, the previously deconfigured
packages (B) cannot be reconfigured again.
:Mandatory: No
:Default:
- An empty string for non-component based installations
- :variable:`CPACK_DEBIAN_PACKAGE_BREAKS` for component-based
installations.
.. versionadded:: 3.4
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_BREAKS` variables.
See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-breaks
.. variable:: CPACK_DEBIAN_PACKAGE_CONFLICTS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS
Sets the `Conflicts` field of the Debian package.
When one binary package declares a conflict with another using a `Conflicts`
field, ``dpkg`` will not allow them to be unpacked on the system at
the same time.
:Mandatory: No
:Default:
- An empty string for non-component based installations
- :variable:`CPACK_DEBIAN_PACKAGE_CONFLICTS` for component-based
installations.
.. versionadded:: 3.4
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONFLICTS` variables.
See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-conflicts
.. note::
This is a stronger restriction than
:variable:`Breaks <CPACK_DEBIAN_PACKAGE_BREAKS>`, which prevents the
broken package from being configured while the breaking package is in
the "Unpacked" state but allows both packages to be unpacked at the same
time.
.. variable:: CPACK_DEBIAN_PACKAGE_PROVIDES
CPACK_DEBIAN_<COMPONENT>_PACKAGE_PROVIDES
Sets the `Provides` field of the Debian package.
A virtual package is one which appears in the `Provides` control field of
another package.
:Mandatory: No
:Default:
- An empty string for non-component based installations
- :variable:`CPACK_DEBIAN_PACKAGE_PROVIDES` for component-based
installations.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-virtual
.. variable:: CPACK_DEBIAN_PACKAGE_REPLACES
CPACK_DEBIAN_<COMPONENT>_PACKAGE_REPLACES
Sets the `Replaces` field of the Debian package.
Packages can declare in their control file that they should overwrite
files in certain other packages, or completely replace other packages.

See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps
.. variable:: CPACK_DEBIAN_PACKAGE_RECOMMENDS
CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS
Sets the ``Recommends`` field of the Debian package.
Allows packages to declare a strong, but not absolute, dependency on other
packages.
:Mandatory: No
:Default:
- An empty string for non-component based installations
- :variable:`CPACK_DEBIAN_PACKAGE_RECOMMENDS` for component-based
installations.
.. versionadded:: 3.4
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_RECOMMENDS` variables.
See https://www.debian.org/doc/debian-policy/ch-relationships.html#s-binarydeps

.. variable:: CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS
.. versionadded:: 3.6
:Mandatory: No
:Default: ``OFF``
Allows to generate shlibs control file automatically. Compatibility is defined by
:variable:`CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY` variable value.
.. note::
Libraries are only considered if they have both library name and version
set. This can be done by setting SOVERSION property with
:command:`set_target_properties` command.
.. variable:: CPACK_DEBIAN_PACKAGE_GENERATE_SHLIBS_POLICY
.. versionadded:: 3.6
Compatibility policy for auto-generated shlibs control file.
:Mandatory: No
:Default: ``=``
Defines compatibility policy for auto-generated shlibs control file.
Possible values: ``=``, ``>=``
See https://www.debian.org/doc/debian-policy/ch-sharedlibs.html#s-sharedlibs-shlibdeps
.. variable:: CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_EXTRA
This variable allow advanced user to add custom script to the
control.tar.gz.
Typical usage is for conffiles, postinst, postrm, prerm.
:Mandatory: No
:Default: None
Usage:
.. code-block:: cmake
set(CPACK_DEBIAN_PACKAGE_CONTROL_EXTRA
"${CMAKE_CURRENT_SOURCE_DIR}/prerm;${CMAKE_CURRENT_SOURCE_DIR}/postrm")
.. versionadded:: 3.4
Per-component :variable:`!CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_EXTRA` variables.
.. variable:: CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION
CPACK_DEBIAN_<COMPONENT>_PACKAGE_CONTROL_STRICT_PERMISSION
.. versionadded:: 3.4
This variable indicates if the Debian policy on control files should be
strictly followed.
:Mandatory: No
:Default: ``FALSE``
Usage:
.. code-block:: cmake
set(CPACK_DEBIAN_PACKAGE_CONTROL_STRICT_PERMISSION TRUE)
This overrides the permissions on the original files, following the rules
set by Debian policy
https://www.debian.org/doc/debian-policy/ch-files.html#s-permissions-owners
.. note::
The original permissions of the files will be used in the final
package unless this variable is set to ``TRUE``.
In particular, the scripts should have the proper executable
flag prior to the generation of the package.
.. variable:: CPACK_DEBIAN_PACKAGE_SOURCE
CPACK_DEBIAN_<COMPONENT>_PACKAGE_SOURCE
.. versionadded:: 3.5
Sets the ``Source`` field of the binary Debian package.
When the binary package name is not the same as the source package name
(in particular when several components/binaries are generated from one
source) the source from which the binary has been generated should be
indicated with the field ``Source``.
:Mandatory: No
:Default:
- An empty string for non-component based installations
- :variable:`CPACK_DEBIAN_PACKAGE_SOURCE` for component-based
installations.
See https://www.debian.org/doc/debian-policy/ch-controlfields.html#s-f-source
.. note::
This value is not interpreted. It is possible to pass an optional
revision number of the referenced source package as well.
Packaging of debug information
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionadded:: 3.13
Dbgsym packages contain debug symbols for debugging packaged binaries.
Dbgsym packaging has its own set of variables:
.. variable:: CPACK_DEBIAN_DEBUGINFO_PACKAGE
CPACK_DEBIAN_<component>_DEBUGINFO_PACKAGE
Enable generation of dbgsym .ddeb package(s).
:Mandatory: No
:Default: ``OFF``
.. note::
Setting this also strips the ELF files in the generated non-dbgsym package,
which results in debuginfo only being available in the dbgsym package.
.. note::
Binaries must contain debug symbols before packaging so use either ``Debug``
or ``RelWithDebInfo`` for :variable:`CMAKE_BUILD_TYPE` variable value.
Additionally, if :variable:`CPACK_STRIP_FILES` is set, the files will be stripped before
they get to the DEB generator, so will not contain debug symbols and
a dbgsym package will not get built. Do not use with :variable:`CPACK_STRIP_FILES`.
Building Debian packages on Windows
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. versionadded:: 3.10
To communicate UNIX file permissions from the install stage
to the CPack DEB generator the ``cmake_mode_t`` NTFS
alternate data stream (ADT) is used.
When a filesystem without ADT support is used only owner read/write
permissions can be preserved.
Reproducible packages
^^^^^^^^^^^^^^^^^^^^^
.. versionadded:: 3.13
The environment variable :envvar:`!SOURCE_DATE_EPOCH` may be set to a UNIX
timestamp, defined as the number of seconds, excluding leap seconds,
since 01 Jan 1970 00:00:00 UTC. If set, the CPack DEB generator will
use its value for timestamps in the package.

The following variables are specific to the DragNDrop installers built
on macOS:
.. variable:: CPACK_DMG_VOLUME_NAME
The volume name of the generated disk image.
:Default: :variable:`CPACK_PACKAGE_FILE_NAME`
.. variable:: CPACK_DMG_FORMAT
The disk image format.
:Default: ``UDZO``
Common values are ``UDRO`` (UDIF read-only), ``UDZO`` (UDIF
zlib-compressed) or ``UDBZ`` (UDIF bzip2-compressed). Refer to ``hdiutil(1)`` for
more information on other available formats.
.. variable:: CPACK_DMG_DS_STORE
Path to a custom ``.DS_Store`` file. This ``.DS_Store`` file can be used to
specify the Finder window position/geometry and layout (such as hidden
toolbars, placement of the icons etc.). This file has to be generated by
the Finder (either manually or through AppleScript) using a normal folder
from which the ``.DS_Store`` file can then be extracted.
.. variable:: CPACK_DMG_DS_STORE_SETUP_SCRIPT
.. versionadded:: 3.5
Path to a custom AppleScript file. This AppleScript is used to generate
a ``.DS_Store`` file which specifies the Finder window position/geometry and
layout (such as hidden toolbars, placement of the icons etc.).
By specifying a custom AppleScript there is no need to use
``CPACK_DMG_DS_STORE``, as the ``.DS_Store`` that is generated by the AppleScript
will be packaged.
.. variable:: CPACK_DMG_BACKGROUND_IMAGE
:Default:
Path to an image file to be used as the background. This file will be
copied to ``.background``/``background.<ext>``, where ``<ext>`` is the original image file
extension. The background image is installed into the image before
``CPACK_DMG_DS_STORE_SETUP_SCRIPT`` is executed or ``CPACK_DMG_DS_STORE`` is
installed. By default no background image is set.
.. variable:: CPACK_DMG_DISABLE_APPLICATIONS_SYMLINK
.. versionadded:: 3.6
Default behavior is to include a symlink to ``/Applications`` in the DMG.
Set this option to ``ON`` to avoid adding the symlink.
.. variable:: CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE
.. versionadded:: 3.23
:Default: ``OFF``
Control whether :variable:`CPACK_RESOURCE_FILE_LICENSE`, if set to a
non-default value, is used as the license agreement provided when
mounting the DMG. If :variable:`!CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE` is
not set, :manual:`cpack(1)` defaults to off.
In a CMake project that uses the :module:`CPack` module to generate
``CPackConfig.cmake``, :variable:`!CPACK_DMG_SLA_USE_RESOURCE_FILE_LICENSE`
must be explicitly enabled by the project to activate the SLA.
See policy :policy:`CMP0133`.
.. note::
This option was added in response to macOS 12.0's deprecation of
the ``hdiutil udifrez`` command to make its use optional.
CPack 3.22 and below always use :variable:`CPACK_RESOURCE_FILE_LICENSE`,
if set to a non-default value, as the DMG license.
.. variable:: CPACK_DMG_SLA_DIR
.. versionadded:: 3.5
Directory where license and menu files for different languages are stored.
Setting this causes CPack to look for a ``<language>.menu.txt`` and
``<language>.license.txt`` or ``<language>.license.rtf`` file for every
language defined in :variable:`CPACK_DMG_SLA_LANGUAGES`. If both this variable and
:variable:`CPACK_RESOURCE_FILE_LICENSE` are set, CPack will only look for the menu
files and use the same license file for all languages. If both
``<language>.license.txt`` and ``<language>.license.rtf`` exist, the ``.txt``
file will be used.
.. versionadded:: 3.17
RTF support.
.. variable:: CPACK_DMG_SLA_LANGUAGES
.. versionadded:: 3.5
Languages for which a license agreement is provided when mounting the
generated DMG. A menu file consists of 9 lines of text. The first line is
is the name of the language itself, uppercase, in English (e.g. German).
The other lines are translations of the following strings:
- Agree
- Disagree
- Print
- Save...
- You agree to the terms of the License Agreement when you click the
"Agree" button.
- Software License Agreement
- This text cannot be saved. The disk may be full or locked, or the file
may be locked.
- Unable to print. Make sure you have selected a printer.
For every language in this list, CPack will try to find files
``<language>.menu.txt`` and ``<language>.license.txt`` in the directory
specified by the :variable:`CPACK_DMG_SLA_DIR` variable.
.. variable:: CPACK_DMG_<component>_FILE_NAME
.. versionadded:: 3.17
File name when packaging ``<component>`` as its own DMG
(:variable:`CPACK_COMPONENTS_GROUPING` set to ``IGNORE``).
:Default: ``CPACK_PACKAGE_FILE_NAME-<component>``
.. variable:: CPACK_DMG_FILESYSTEM
.. versionadded:: 3.21
:Default: ``HFS+``
The filesystem format. Common values are ``APFS`` and ``HFS+``.
See ``man hdiutil`` for a full list of supported formats.
.. variable:: CPACK_COMMAND_HDIUTIL
Path to the ``hdiutil(1)`` command used to operate on disk image files on
macOS. This variable can be used to override the automatically detected
command (or specify its location if the auto-detection fails to find it).
.. variable:: CPACK_COMMAND_SETFILE
Path to the ``SetFile(1)`` command used to set extended attributes on files and
directories on macOS. This variable can be used to override the
automatically detected command (or specify its location if the
auto-detection fails to find it).
.. variable:: CPACK_COMMAND_REZ
Path to the ``Rez(1)`` command used to compile resources on macOS. This
variable can be used to override the automatically detected command (or
specify its location if the auto-detection fails to find it).

CPack External Generator
------------------------
.. versionadded:: 3.13
CPack provides many generators to create packages for a variety of platforms
and packaging systems. The intention is for CMake/CPack to be a complete
end-to-end solution for building and packaging a software project. However, it
may not always be possible to use CPack for the entire packaging process, due
to either technical limitations or policies that require the use of certain
tools. For this reason, CPack provides the "External" generator, which allows
external packaging software to take advantage of some of the functionality
provided by CPack, such as component installation and the dependency graph.
Integration with External Packaging Tools
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The CPack External generator generates a ``.json`` file containing the
CPack internal metadata, which gives external software information
on how to package the software. External packaging software may itself
invoke CPack, consume the generated metadata,
install and package files as required.
Alternatively CPack can invoke an external packaging software
through an optional custom CMake script in
:variable:`CPACK_EXTERNAL_PACKAGE_SCRIPT` instead.
Staging of installation files may also optionally be
taken care of by the generator when enabled through the
:variable:`CPACK_EXTERNAL_ENABLE_STAGING` variable.
JSON Format
^^^^^^^^^^^
The JSON metadata file contains a list of CPack components and component groups,
the various options passed to :command:`cpack_add_component` and
:command:`cpack_add_component_group`, the dependencies between the components
and component groups, and various other options passed to CPack.
The JSON's root object will always provide two fields:
``formatVersionMajor`` and ``formatVersionMinor``, which are always integers
that describe the output format of the generator. Backwards-compatible changes
to the output format (for example, adding a new field that didn't exist before)
cause the minor version to be incremented, and backwards-incompatible changes
(for example, deleting a field or changing its meaning) cause the major version
to be incremented and the minor version reset to 0. The format version is
always of the format ``major.minor``. In other words, it always has exactly two
parts, separated by a period.
You can request one or more specific versions of the output format as described
below with :variable:`CPACK_EXTERNAL_REQUESTED_VERSIONS`. The output format will
have a major version that exactly matches the requested major version, and a
minor version that is greater than or equal to the requested minor version. If
no version is requested with :variable:`CPACK_EXTERNAL_REQUESTED_VERSIONS`, the
latest known major version is used by default. Currently, the only supported
format is 1.0, which is described below.
Version 1.0
***********
In addition to the standard format fields, format version 1.0 provides the
following fields in the root:
``components``
The ``components`` field is an object with component names as the keys and
objects describing the components as the values. The component objects have
the following fields:
``name``
The name of the component. This is always the same as the key in the
``components`` object.
``displayName``
The value of the ``DISPLAY_NAME`` field passed to
:command:`cpack_add_component`.
``description``
The value of the ``DESCRIPTION`` field passed to
:command:`cpack_add_component`.
``isHidden``
True if ``HIDDEN`` was passed to :command:`cpack_add_component`, false if
it was not.
``isRequired``
True if ``REQUIRED`` was passed to :command:`cpack_add_component`, false if
it was not.
``isDisabledByDefault``
True if ``DISABLED`` was passed to :command:`cpack_add_component`, false if
it was not.
``group``
Only present if ``GROUP`` was passed to :command:`cpack_add_component`. If
so, this field is a string value containing the component's group.
``dependencies``
An array of components the component depends on. This contains the values
in the ``DEPENDS`` argument passed to :command:`cpack_add_component`. If no
``DEPENDS`` argument was passed, this is an empty list.
``installationTypes``
An array of installation types the component is part of. This contains the
values in the ``INSTALL_TYPES`` argument passed to
:command:`cpack_add_component`. If no ``INSTALL_TYPES`` argument was
passed, this is an empty list.
``isDownloaded``
True if ``DOWNLOADED`` was passed to :command:`cpack_add_component`, false
if it was not.
``archiveFile``
The name of the archive file passed with the ``ARCHIVE_FILE`` argument to
:command:`cpack_add_component`. If no ``ARCHIVE_FILE`` argument was passed,
this is an empty string.
``componentGroups``
The ``componentGroups`` field is an object with component group names as the
keys and objects describing the component groups as the values. The component
group objects have the following fields:
``name``
The name of the component group. This is always the same as the key in the
``componentGroups`` object.
``displayName``
The value of the ``DISPLAY_NAME`` field passed to
:command:`cpack_add_component_group`.
``description``
The value of the ``DESCRIPTION`` field passed to
:command:`cpack_add_component_group`.
``parentGroup``
Only present if ``PARENT_GROUP`` was passed to
:command:`cpack_add_component_group`. If so, this field is a string value
containing the component group's parent group.
``isExpandedByDefault``
True if ``EXPANDED`` was passed to :command:`cpack_add_component_group`,
false if it was not.
``isBold``
True if ``BOLD_TITLE`` was passed to :command:`cpack_add_component_group`,
false if it was not.
``components``
An array of names of components that are direct members of the group
(components that have this group as their ``GROUP``). Components of
subgroups are not included.
``subgroups``
An array of names of component groups that are subgroups of the group
(groups that have this group as their ``PARENT_GROUP``).
``installationTypes``
The ``installationTypes`` field is an object with installation type names as
the keys and objects describing the installation types as the values. The
installation type objects have the following fields:
``name``
The name of the installation type. This is always the same as the key in
the ``installationTypes`` object.
``displayName``
The value of the ``DISPLAY_NAME`` field passed to
:command:`cpack_add_install_type`.
``index``
The integer index of the installation type in the list.
``projects``
The ``projects`` field is an array of objects describing CMake projects which
comprise the CPack project. The values in this field are derived from
:variable:`CPACK_INSTALL_CMAKE_PROJECTS`. In most cases, this will be only a
single project. The project objects have the following fields:
``projectName``
The project name passed to :variable:`CPACK_INSTALL_CMAKE_PROJECTS`.
``component``
The name of the component or component set which comprises the project.
``directory``
The build directory of the CMake project. This is the directory which
contains the ``cmake_install.cmake`` script.

if it is not.
``errorOnAbsoluteInstallDestination``
True if :variable:`CPACK_ERROR_ON_ABSOLUTE_INSTALL_DESTINATION` is true,
false if it is not.
Variables specific to CPack External generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
.. variable:: CPACK_EXTERNAL_REQUESTED_VERSIONS
This variable is used to request a specific version of the CPack External
generator. It is a list of ``major.minor`` values, separated by semicolons.
If this variable is set to a non-empty value, the CPack External generator
will iterate through each item in the list to search for a version that it
knows how to generate. Requested versions should be listed in order of
descending preference by the client software, as the first matching version
in the list will be generated.
The generator knows how to generate the version if it has a versioned
generator whose major version exactly matches the requested major version,
and whose minor version is greater than or equal to the requested minor
version. For example, if ``CPACK_EXTERNAL_REQUESTED_VERSIONS`` contains 1.0, and
the CPack External generator knows how to generate 1.1, it will generate 1.1.
If the generator doesn't know how to generate a version in the list, it skips
the version and looks at the next one. If it doesn't know how to generate any
of the requested versions, an error is thrown.
If this variable is not set, or is empty, the CPack External generator will
generate the highest major and minor version that it knows how to generate.
If an invalid version is encountered in ``CPACK_EXTERNAL_REQUESTED_VERSIONS`` (one
that doesn't match ``major.minor``, where ``major`` and ``minor`` are
integers), it is ignored.
.. variable:: CPACK_EXTERNAL_ENABLE_STAGING
This variable can be set to true to enable optional installation
into a temporary staging area which can then be picked up
and packaged by an external packaging tool.
The top level directory used by CPack for the current packaging
task is contained in ``CPACK_TOPLEVEL_DIRECTORY``.
It is automatically cleaned up on each run before packaging is initiated
and can be used for custom temporary files required by
the external packaging tool.
It also contains the staging area ``CPACK_TEMPORARY_DIRECTORY``
into which CPack performs the installation when staging is enabled.
.. variable:: CPACK_EXTERNAL_PACKAGE_SCRIPT
This variable can optionally specify the full path to
a CMake script file to be run as part of the CPack invocation.
It is invoked after (optional) staging took place and may
run an external packaging tool. The script has access to
the variables defined by the CPack config file.
.. variable:: CPACK_EXTERNAL_BUILT_PACKAGES
.. versionadded:: 3.19
The ``CPACK_EXTERNAL_PACKAGE_SCRIPT`` script may set this list variable to the
full paths of generated package files. CPack will copy these files from the
staging directory back to the top build directory and possibly produce
checksum files if the :variable:`CPACK_PACKAGE_CHECKSUM` is set.

CPack FreeBSD Generator
-----------------------
.. versionadded:: 3.10
The built in (binary) CPack FreeBSD (pkg) generator (Unix only)
Variables affecting the CPack FreeBSD (pkg) generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
- .. versionadded:: 3.18
:variable:`CPACK_ARCHIVE_THREADS`
Variables specific to CPack FreeBSD (pkg) generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The CPack FreeBSD generator may be used to create pkg(8) packages -- these may
be used on FreeBSD, DragonflyBSD, NetBSD, OpenBSD, but also on Linux or OSX,
depending on the installed package-management tools -- using :module:`CPack`.
The CPack FreeBSD generator is a :module:`CPack` generator and uses the
:variable:`!CPACK_XXX` variables used by :module:`CPack`. It tries to re-use packaging
information that may already be specified for Debian packages for the
:cpack_gen:`CPack DEB Generator`. It also tries to re-use RPM packaging
information when Debian does not specify.
The CPack FreeBSD generator should work on any host with libpkg installed. The
packages it produces are specific to the host architecture and ABI.
The CPack FreeBSD generator sets package-metadata through
:variable:`!CPACK_FREEBSD_XXX` variables. The CPack FreeBSD generator, unlike the
CPack Deb generator, does not specially support componentized packages; a
single package is created from all the software artifacts created through
CMake.
All of the variables can be set specifically for FreeBSD packaging in
the CPackConfig file or in CMakeLists.txt, but most of them have defaults
that use general settings (e.g. :variable:`CMAKE_PROJECT_NAME`) or Debian-specific
variables when those make sense (e.g. the homepage of an upstream project
is usually unchanged by the flavor of packaging). When there is no Debian
information to fall back on, but the RPM packaging has it, fall back to
the RPM information (e.g. package license).
.. variable:: CPACK_FREEBSD_PACKAGE_NAME
Sets the package name (in the package manifest, but also affects the
output filename).
:Mandatory: Yes
:Default:
- :variable:`CPACK_PACKAGE_NAME` (this is always set by CPack itself,
based on CMAKE_PROJECT_NAME).
.. variable:: CPACK_FREEBSD_PACKAGE_COMMENT
Sets the package comment. This is the short description displayed by
pkg(8) in standard "pkg info" output.
:Mandatory: Yes
:Default:
- :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY` (this is always set
by CPack itself, if nothing else sets it explicitly).
.. variable:: CPACK_FREEBSD_PACKAGE_DESCRIPTION
Sets the package description. This is the long description of the package,
given by "pkg info" with a specific package as argument.
:Mandatory: Yes
:Default:
- :variable:`CPACK_DEBIAN_PACKAGE_DESCRIPTION` (this may be set already
for Debian packaging, so it is used as a fallback).
- :variable:`CPACK_PACKAGE_DESCRIPTION_SUMMARY` (this is always set
by CPack itself, if nothing else sets it explicitly).
- :variable:`PROJECT_DESCRIPTION` (this can be set with the ``DESCRIPTION``
parameter for :command:`project`).
.. variable:: CPACK_FREEBSD_PACKAGE_WWW
The URL of the web site for this package, preferably (when applicable) the
site from which the original source can be obtained and any additional
upstream documentation or information may be found.
:Mandatory: Yes
:Default:
- :variable:`CPACK_PACKAGE_HOMEPAGE_URL`, or if that is not set,
- :variable:`CPACK_DEBIAN_PACKAGE_HOMEPAGE` (this may be set already
for Debian packaging, so it is used as a fallback).
.. versionadded:: 3.12
The :variable:`!CPACK_PACKAGE_HOMEPAGE_URL` variable.
.. variable:: CPACK_FREEBSD_PACKAGE_LICENSE
The license, or licenses, which apply to this software package. This must
be one or more license-identifiers that pkg recognizes as acceptable license
identifiers (e.g. "GPLv2").
:Mandatory: Yes
:Default:
- :variable:`CPACK_RPM_PACKAGE_LICENSE`
.. variable:: CPACK_FREEBSD_PACKAGE_LICENSE_LOGIC
This variable is only of importance if there is more than one license.
The default is "single", which is only applicable to a single license.
Other acceptable values are determined by pkg -- those are "dual" or "multi" --
meaning choice (OR) or simultaneous (AND) application of the licenses.
:Mandatory: No
:Default: single
.. variable:: CPACK_FREEBSD_PACKAGE_MAINTAINER
The FreeBSD maintainer (e.g. ``kde@freebsd.org``) of this package.
:Mandatory: Yes
:Default: none
.. variable:: CPACK_FREEBSD_PACKAGE_ORIGIN
The origin (ports label) of this package; for packages built by CPack
outside of the ports system this is of less importance. The default
puts the package somewhere under ``misc/``, as a stopgap.
:Mandatory: Yes
:Default: ``misc/<package name>``
.. variable:: CPACK_FREEBSD_PACKAGE_CATEGORIES
The ports categories where this package lives (if it were to be built
from ports). If none is set a single category is determined based on
the package origin.
:Mandatory: Yes
:Default: derived from ``ORIGIN``
.. variable:: CPACK_FREEBSD_PACKAGE_DEPS
A list of package origins that should be added as package dependencies.
These are in the form ``<category>/<packagename>``, e.g. ``x11/libkonq``.
No version information needs to be provided (this is not included
in the manifest).
:Mandatory: No

.. contents::
Overview
^^^^^^^^
This :manual:`cpack generator <cpack-generators(7)>` generates
configuration and meta information for the `Qt Installer Framework
<https://doc.qt.io/qtinstallerframework/index.html>`_ (QtIFW),
and runs QtIFW tools to generate a Qt installer.
QtIFW provides tools and utilities to create installers for
the platforms supported by `Qt <https://www.qt.io>`_: Linux,
Microsoft Windows, and macOS.
To make use of this generator, QtIFW needs to be installed.
The :module:`CPackIFW` module looks for the location of the
QtIFW command-line utilities, and defines several commands to
control the behavior of this generator. See `Hints for Finding QtIFW`_.

The default value of this variable is computed by CPack and contains
all repositories added with :command:`cpack_ifw_add_repository`
or updated with :command:`cpack_ifw_update_repository`.
.. variable:: CPACK_IFW_DOWNLOAD_ALL
If this is ``ON``, all components will be downloaded. If not set, the
behavior is determined by whether :command:`cpack_configure_downloads` has
been called with the ``ALL`` option or not.
.. variable:: CPACK_IFW_PACKAGE_PRODUCT_IMAGES
.. versionadded:: 3.23
A list of images to be shown on the ``PerformInstallationPage``. These
must be absolute paths and the images must be in PNG format.
This feature is available for QtIFW 4.0.0 and later.
.. variable:: CPACK_IFW_PACKAGE_RUN_PROGRAM
.. versionadded:: 3.23
Command executed after the installer is finished, if the user accepts the
action. Provide the full path to the application, as found when installed.
This typically means the path should begin with the QtIFW predefined variable
``@TargetDir@``.
This feature is available for QtIFW 4.0.0 and later.
.. variable:: CPACK_IFW_PACKAGE_RUN_PROGRAM_ARGUMENTS
.. versionadded:: 3.23
List of arguments passed to the program specified in
:variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM`.
This feature is available for QtIFW 4.0.0 and later.
.. variable:: CPACK_IFW_PACKAGE_RUN_PROGRAM_DESCRIPTION
.. versionadded:: 3.23
Text shown next to the check box for running the program after the
installation. If :variable:`CPACK_IFW_PACKAGE_RUN_PROGRAM` is set but no
description is provided, QtIFW will use a default message like
``Run <Name> now``.
This feature is available for QtIFW 4.0.0 and later.
.. variable:: CPACK_IFW_PACKAGE_SIGNING_IDENTITY
.. versionadded:: 3.23
Allows specifying a code signing identity to be used for signing the generated
app bundle. Only available on macOS, ignored on other platforms.
.. variable:: CPACK_IFW_ARCHIVE_FORMAT
.. versionadded:: 3.23
Set the format used when packaging new component data archives. If you omit
this option, the ``7z`` format will be used as a default. Supported formats:
* 7z
* zip
* tar.gz
* tar.bz2
* tar.xz
.. note::
If the Qt Installer Framework tools were built without libarchive support,
only ``7z`` format is supported.
This feature is available for QtIFW 4.2.0 and later.
.. variable:: CPACK_IFW_ARCHIVE_COMPRESSION
.. versionadded:: 3.23
Archive compression level. The allowable values are:
* 0 (*No compression*)
* 1 (*Fastest compression*)
* 3 (*Fast compression*)
* 5 (*Normal compression*)
* 7 (*Maximum compression*)
* 9 (*Ultra compression*)
If this variable is not set, QtIFW will use a default compression level,
which will typically be 5 (*Normal compression*).
.. note::
Some formats do not support all the possible values. For example ``zip``
compression only supports values from 1 to 7.
This feature is available for QtIFW 4.2.0 and later.
Components
""""""""""
.. variable:: CPACK_IFW_RESOLVE_DUPLICATE_NAMES
Resolve duplicate names when installing components with groups.
.. variable:: CPACK_IFW_PACKAGES_DIRECTORIES
Additional prepared packages directories that will be used to resolve
dependent components.
.. variable:: CPACK_IFW_REPOSITORIES_DIRECTORIES
.. versionadded:: 3.10
Additional prepared repository directories that will be used to resolve and
repack dependent components.
This feature is available for QtIFW 3.1 and later.
QtIFW Tools
"""""""""""
.. variable:: CPACK_IFW_FRAMEWORK_VERSION
.. versionadded:: 3.3
The version of the QtIFW tools that will be used. This variable is set
by the :module:`CPackIFW` module.
The following variables provide the locations of the QtIFW
command-line tools as discovered by the :module:`CPackIFW` module.
These variables are cached, and may be configured if needed.
.. variable:: CPACK_IFW_ARCHIVEGEN_EXECUTABLE
.. versionadded:: 3.19
The path to ``archivegen``.
.. variable:: CPACK_IFW_BINARYCREATOR_EXECUTABLE
The path to ``binarycreator``.
.. variable:: CPACK_IFW_REPOGEN_EXECUTABLE
The path to ``repogen``.
.. variable:: CPACK_IFW_INSTALLERBASE_EXECUTABLE
The path to ``installerbase``.
.. variable:: CPACK_IFW_DEVTOOL_EXECUTABLE
The path to ``devtool``.
Hints for Finding QtIFW
"""""""""""""""""""""""
Generally, the CPack ``IFW`` generator automatically finds QtIFW tools.
The following (in order of precedence) can also be set to augment the
locations normally searched by :command:`find_program`:
.. variable:: CPACK_IFW_ROOT
.. versionadded:: 3.9
CMake variable
.. envvar:: CPACK_IFW_ROOT
.. versionadded:: 3.9
Environment variable
.. variable:: QTIFWDIR
CMake variable
.. envvar:: QTIFWDIR
Environment variable
.. note::
The specified path should not contain ``bin`` at the end
(for example: ``D:\\DevTools\\QtIFW2.0.5``).
Other Settings
^^^^^^^^^^^^^^
Online installer
""""""""""""""""
By default, this generator generates an *offline installer*. This means
that all packaged files are fully contained in the installer executable.
In contrast, an *online installer* will download some or all components from
a remote server.
The ``DOWNLOADED`` option in the :command:`cpack_add_component` command
specifies that a component is to be downloaded. Alternatively, the ``ALL``
option in the :command:`cpack_configure_downloads` command specifies that
`all` components are to be be downloaded.
The :command:`cpack_ifw_add_repository` command and the
:variable:`CPACK_IFW_DOWNLOAD_ALL` variable allow for more specific
configuration.
When there are online components, CPack will write them to archive files.
The help page of the :module:`CPackComponent` module, especially the section
on the :command:`cpack_configure_downloads` function, explains how to make
these files accessible from a download URL.
Internationalization
""""""""""""""""""""
.. versionadded:: 3.9
Some variables and command arguments support internationalization via
CMake script. This is an optional feature.
Installers created by QtIFW tools have built-in support for
internationalization and many phrases are localized to many languages,
but this does not apply to the description of your components and groups.
Localization of the description of your components and groups is useful for
users of your installers.
A localized variable or argument can contain a single default value, and
after that a set of pairs with the name of the locale and the localized value.
For example:
.. code-block:: cmake
set(LOCALIZABLE_VARIABLE "Default value"
en "English value"
en_US "American value"
en_GB "Great Britain value"
)

CPack Inno Setup Generator
--------------------------
.. versionadded:: 3.27
Inno Setup is a free installer for Windows programs by Jordan Russell and
Martijn Laan (https://jrsoftware.org/isinfo.php).
This documentation explains Inno Setup generator specific options.
The generator provides a lot of options like components. Unfortunately, not
all features (e.g. component dependencies) are currently supported by
Inno Setup and they're ignored by the generator for now.
CPack requires Inno Setup 6 or greater and only works on Windows.
Variables specific to CPack Inno Setup generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
You can use the following variables to change the behavior of the CPack
``INNOSETUP`` generator:
General
"""""""
None of the following variables is required to be set for the Inno Setup
generator to work. If a variable is marked as mandatory below but not set,
its default value is taken.
The variables can also contain Inno Setup constants like ``{app}``. Please
refer to the documentation of Inno Setup for more information.
If you're asked to provide the path to any file, you can always give an
absolute path or in most cases the relative path from the top-level directory
where all files being installed by an :command:`install` instruction reside.
CPack tries to escape quotes and other special characters for you. However,
using special characters could cause problems.
The following variable simplifies the usage of Inno Setup in CMake:
.. variable:: CPACK_INNOSETUP_USE_CMAKE_BOOL_FORMAT
Inno Setup only uses ``yes`` or ``no`` as boolean formats meanwhile CMake
uses a lot of alternative formats like ``ON`` or ``OFF``. Having this option
turned on enables an automatic conversion.
Consider the following example:
.. code-block:: cmake
set(CMAKE_INNOSETUP_SETUP_AllowNoIcons OFF)
If this option is turned on, the following line will be created in the output
script: ``AllowNoIcons=no``.
Else, the following erroneous line will be created: ``AllowNoIcons=OFF``
The conversion is enabled in every Inno Setup specific variable.
:Mandatory: Yes
:Default: ``ON``
Setup Specific Variables
""""""""""""""""""""""""
.. variable:: CPACK_INNOSETUP_ARCHITECTURE
One of ``x86``, ``x64``, ``arm64`` or ``ia64``. This variable specifies the
target architecture of the installer. This also affects the Program Files
folder or registry keys being used.
CPack tries to determine the correct value with a try compile (see
:variable:`CMAKE_SIZEOF_VOID_P`), but this option can be manually specified
too (especially when using ``ia64`` or cross-platform compilation).
:Mandatory: Yes
:Default: Either ``x86`` or ``x64`` depending on the results of the try-compile
.. variable:: CPACK_INNOSETUP_INSTALL_ROOT
If you don't want the installer to create the installation directory under
Program Files, you've to specify the installation root here.
The full directory of the installation will be:
``${CPACK_INNOSETUP_INSTALL_ROOT}/${CPACK_PACKAGE_INSTALL_DIRECTORY}``.
:Mandatory: Yes
:Default: ``{autopf}``
.. variable:: CPACK_INNOSETUP_ALLOW_CUSTOM_DIRECTORY
If turned on, the installer allows the user to change the installation
directory providing an extra wizard page.
:Mandatory: Yes
:Default: ``ON``
.. variable:: CPACK_INNOSETUP_PROGRAM_MENU_FOLDER
The initial name of the start menu folder being created.
If this variable is set to ``.``, then no separate folder is created,
application shortcuts will appear in the top-level start menu folder.
:Mandatory: Yes
:Default: The value of :variable:`CPACK_PACKAGE_NAME`
.. variable:: CPACK_INNOSETUP_LANGUAGES
A :ref:`semicolon-separated list <CMake Language Lists>` of languages you want
Inno Setup to include.
Currently available: ``armenian``, ``brazilianPortuguese``, ``bulgarian``,
``catalan``, ``corsican``, ``czech``, ``danish``, ``dutch``, ``english``,
``finnish``, ``french``, ``german``, ``hebrew``, ``icelandic``, ``italian``,
``japanese``, ``norwegian``, ``polish``, ``portuguese``, ``russian``,
``slovak``, ``slovenian``, ``spanish``, ``turkish`` and ``ukrainian``.
This list might differ depending on the version of Inno Setup.
:Mandatory: Yes
:Default: ``english``
.. variable:: CPACK_INNOSETUP_IGNORE_LICENSE_PAGE
If you don't specify a license file using
:variable:`CPACK_RESOURCE_FILE_LICENSE`, CPack uses a file for demonstration
purposes. If you want the installer to ignore license files at all, you can
enable this option.
:Mandatory: Yes
:Default: ``OFF``
.. variable:: CPACK_INNOSETUP_IGNORE_README_PAGE
If you don't specify a readme file using
:variable:`CPACK_RESOURCE_FILE_README`, CPack uses a file for demonstration
purposes. If you want the installer to ignore readme files at all, you can
enable this option. Make sure the option is disabled when using
a custom readme file.
:Mandatory: Yes
:Default: ``ON``
.. variable:: CPACK_INNOSETUP_PASSWORD
Enables password protection and file encryption with the given password.
:Mandatory: No
.. variable:: CPACK_INNOSETUP_USE_MODERN_WIZARD
Enables the modern look and feel provided by Inno Setup. If this option is
turned off, the classic style is used instead. Images and icon files are
also affected.
:Mandatory: Yes
:Default: ``OFF`` because of compatibility reasons
.. variable:: CPACK_INNOSETUP_ICON_FILE
The path to a custom installer ``.ico`` file.
Use :variable:`CPACK_PACKAGE_ICON` to customize the bitmap file being shown
in the wizard.
:Mandatory: No
.. variable:: CPACK_INNOSETUP_SETUP_<directive>
This group allows adapting any of the ``[Setup]`` section directives provided
by Inno Setup where ``directive`` is its name.
Here are some examples:
.. code-block:: cmake
set(CPACK_INNOSETUP_SETUP_WizardSmallImageFile "my_bitmap.bmp")
set(CPACK_INNOSETUP_SETUP_AllowNoIcons OFF) # This requires CPACK_INNOSETUP_USE_CMAKE_BOOL_FORMAT to be on
All of these variables have higher priority than the others.
Consider the following example:
.. code-block:: cmake
set(CPACK_INNOSETUP_SETUP_Password "admin")
set(CPACK_INNOSETUP_PASSWORD "secret")
The password will be ``admin`` at the end because ``CPACK_INNOSETUP_PASSWORD``
has less priority than ``CPACK_INNOSETUP_SETUP_Password``.
:Mandatory: No
File Specific Variables
"""""""""""""""""""""""
Although all files being installed by an :command:`install` instruction are
automatically processed and added to the installer, there are some variables
to customize the installation process.
Before using executables (only ``.exe`` or ``.com``) in shortcuts
(e.g. :variable:`CPACK_CREATE_DESKTOP_LINKS`) or ``[Run]`` entries, you've to
add the raw file name (without path and extension) to
:variable:`CPACK_PACKAGE_EXECUTABLES` and create a start menu shortcut
for them.
If you have two files with the same raw name (e.g. ``a/executable.exe`` and
``b/executable.com``), an entry in the section is created twice. This will
result in undefined behavior and is not recommended.
.. variable:: CPACK_INNOSETUP_CUSTOM_INSTALL_INSTRUCTIONS
This variable should contain a
:ref:`semicolon-separated list <CMake Language Lists>` of pairs ``path``,
``instruction`` and can be used to customize the install command being
automatically created for each file or directory.
CPack creates the following Inno Setup instruction for every file...
.. code-block::
Source: "absolute\path\to\my_file.txt"; DestDir: "{app}"; Flags: ignoreversion
...and the following line for every directory:
.. code-block::
Name: "{app}\my_folder"
You might want to change the destination directory or the flags of
``my_file.txt``. Since we can also provide a relative path, the line you'd
like to have, is the following:
.. code-block::
Source: "my_file.txt"; DestDir: "{userdocs}"; Flags: ignoreversion uninsneveruninstall
You would do this by using ``my_file.txt`` as ``path`` and
``Source: "my_file.txt"; DestDir: "{userdocs}"; Flags: ignoreversion uninsneveruninstall``
as ``instruction``.
You've to take care of the `escaping problem <https://cmake.org/cmake/help/book/mastering-cmake/chapter/Packaging%20With%20CPack.html#adding-custom-cpack-options>`_.
So the CMake command would be:
.. code-block:: cmake
set(CPACK_INNOSETUP_CUSTOM_INSTALL_INSTRUCTIONS "my_file.txt;Source: \\\"my_file.txt\\\"\\; DestDir: \\\"{userdocs}\\\"\\; Flags: ignoreversion uninsneveruninstall")
To improve readability, you should go around the escaping problem by using
:variable:`CPACK_VERBATIM_VARIABLES` or by placing the instruction into a
separate CPack project config file.
If you customize the install instruction of a specific file, you lose the
connection to its component. To go around, manually add
``Components: <component>``. You also need to add its shortcuts and ``[Run]``
entries by yourself in a custom section, since the executable won't be found
anymore by :variable:`CPACK_PACKAGE_EXECUTABLES`.
Here's another example (Note: You've to go around the escaping problem for
the example to work):
.. code-block:: cmake
set(CPACK_INNOSETUP_CUSTOM_INSTALL_INSTRUCTIONS
"component1/my_folder" "Name: \"{userdocs}\\my_folder\"\; Components: component1"
"component2/my_folder2/my_file.txt" "Source: \"component2\\my_folder2\\my_file.txt\"\; DestDir: \"{app}\\my_folder2\\my_file.txt\"\; Flags: ignoreversion uninsneveruninstall\; Components: component2")
:Mandatory: No
.. variable:: CPACK_INNOSETUP_MENU_LINKS
This variable should contain a
:ref:`semicolon-separated list <CMake Language Lists>` of pairs ``link``,
``link name`` and can be used to add shortcuts into the start menu folder
beside those of the executables (see :variable:`CPACK_PACKAGE_EXECUTABLES`).
While ``link name`` is the label, ``link`` can be a URL or a path relative to
the installation directory.
Here's an example:
.. code-block:: cmake
set(CPACK_INNOSETUP_MENU_LINKS
"doc/cmake-@CMake_VERSION_MAJOR@.@CMake_VERSION_MINOR@/cmake.html"
"CMake Help" "https://cmake.org" "CMake Web Site")
:Mandatory: No
.. variable:: CPACK_INNOSETUP_CREATE_UNINSTALL_LINK
If this option is turned on, a shortcut to the application's uninstaller is
automatically added to the start menu folder.
:Mandatory: Yes
:Default: ``OFF``
.. variable:: CPACK_INNOSETUP_RUN_EXECUTABLES
A :ref:`semicolon-separated list <CMake Language Lists>` of executables being
specified in :variable:`CPACK_PACKAGE_EXECUTABLES` which the user can run
when the installer finishes.
They're internally added to the ``[Run]`` section.
:Mandatory: No
Components Specific Variables
"""""""""""""""""""""""""""""
The generator supports components and also downloaded components. However,
there are some features of components that aren't supported yet (especially
component dependencies). These variables are ignored for now.
CPack will change a component's name in Inno Setup if it has a parent group
for technical reasons. Consider using ``group\component`` as component name in
Inno Setup scripts if you have the component ``component`` and its parent
group ``group``.
Here are some additional variables for components:
.. variable:: CPACK_INNOSETUP_<compName>_INSTALL_DIRECTORY
If you don't want the component ``compName`` to be installed under ``{app}``,
you've to specify its installation directory here.
:Mandatory: No
.. variable:: CPACK_INNOSETUP_VERIFY_DOWNLOADS
This option only affects downloaded components.
If this option is turned on, the hashes of the downloaded archives are
calculated during compile and
download time. The installer will only proceed if they match.
:Mandatory: Yes
:Default: ``ON``
Compilation and Scripting Specific Variables
""""""""""""""""""""""""""""""""""""""""""""
.. variable:: CPACK_INNOSETUP_EXECUTABLE
The filename of the Inno Setup Script Compiler command.
:Mandatory: Yes
:Default: ``ISCC``
.. variable:: CPACK_INNOSETUP_EXECUTABLE_ARGUMENTS
A :ref:`semicolon-separated list <CMake Language Lists>` of extra
command-line options for the Inno Setup Script Compiler command.
For example: ``/Qp;/Smysigntool=$p``
Take care of the `escaping problem <https://cmake.org/cmake/help/book/mastering-cmake/chapter/Packaging%20With%20CPack.html#adding-custom-cpack-options>`_.
:Mandatory: No
.. variable:: CPACK_INNOSETUP_DEFINE_<macro>
This group allows to add custom define directives as command-line options to
the Inno Setup Preprocessor command. Each entry emulates a
``#define public <macro>`` directive. Its macro is accessible from anywhere
(``public``), so it can also be used in extra script files.
Macro names must not contain any special characters. Refer to the Inno Setup
Preprocessor documentation for the detailed rules.
Consider the following example:
.. code-block:: cmake
# The following line emulates: #define public MyMacro "Hello, World!"
set(CPACK_INNOSETUP_DEFINE_MyMacro "Hello, World!")
At this point, you can use ``MyMacro`` anywhere. For example in the following
extra script:
.. code-block::
AppComments={#emit "'My Macro' has the value: " + MyMacro}
Take care of the `escaping problem <https://cmake.org/cmake/help/book/mastering-cmake/chapter/Packaging%20With%20CPack.html#adding-custom-cpack-options>`_.
:Mandatory: No
.. variable:: CPACK_INNOSETUP_EXTRA_SCRIPTS
A :ref:`semicolon-separated list <CMake Language Lists>` of paths to
additional ``.iss`` script files to be processed.
They're internally included at the top of the output script file using a
``#include`` directive.
You can add any section in your file to extend the installer (e.g. adding
additional tasks or registry keys). Prefer using
:variable:`CPACK_INNOSETUP_SETUP_<directive>` when extending the
``[Setup]`` section.
:Mandatory: No
.. variable:: CPACK_INNOSETUP_CODE_FILES
A :ref:`semicolon-separated list <CMake Language Lists>` of paths to
additional Pascal files to be processed.
This variable is actually the same as
:variable:`CPACK_INNOSETUP_EXTRA_SCRIPTS`, except you don't have to
add ``[Code]`` at the top of your file. Never change the current section in
a code file. This will result in undefined behavior! Treat them as normal
Pascal scripts instead.
Code files are included at the very bottom of the output script.
:Mandatory: No

CPack NuGet Generator
---------------------
.. versionadded:: 3.12
When build a NuGet package there is no direct way to control an output
filename due a lack of the corresponding CLI option of NuGet, so there
is no :variable:`!CPACK_NUGET_PACKAGE_FILE_NAME` variable. To form the output filename
NuGet uses the package name and the version according to its built-in rules.
Also, be aware that including a top level directory
(:variable:`CPACK_INCLUDE_TOPLEVEL_DIRECTORY`) is ignored by this generator.
Variables specific to CPack NuGet generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The CPack NuGet generator may be used to create NuGet packages using
:module:`CPack`. The CPack NuGet generator is a :module:`CPack` generator thus
it uses the :variable:`!CPACK_XXX` variables used by :module:`CPack`.
The CPack NuGet generator has specific features which are controlled by the
specifics :variable:`!CPACK_NUGET_XXX` variables. In the "one per group" mode
(see :variable:`CPACK_COMPONENTS_GROUPING`), ``<compName>`` placeholder
in the variables below would contain a group name (uppercased and turned into
a "C" identifier).

CPack productbuild Generator
----------------------------
.. versionadded:: 3.7
productbuild CPack generator (macOS).
Variables specific to CPack productbuild generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following variable is specific to installers built on Mac
macOS using ProductBuild:
.. variable:: CPACK_COMMAND_PRODUCTBUILD
Path to the ``productbuild(1)`` command used to generate a product archive for
the macOS Installer or Mac App Store. This variable can be used to override
the automatically detected command (or specify its location if the
auto-detection fails to find it).
.. variable:: CPACK_PRODUCTBUILD_IDENTIFIER
.. versionadded:: 3.23
Set the unique (non-localized) product identifier to be associated with the
product (i.e., ``com.kitware.cmake``). Any component product names will be
appended to this value.
.. variable:: CPACK_PRODUCTBUILD_IDENTITY_NAME
.. versionadded:: 3.8
Adds a digital signature to the resulting package.
.. variable:: CPACK_PRODUCTBUILD_KEYCHAIN_PATH
.. versionadded:: 3.8
Specify a specific keychain to search for the signing identity.
.. variable:: CPACK_COMMAND_PKGBUILD
Path to the ``pkgbuild(1)`` command used to generate an macOS component package
on macOS. This variable can be used to override the automatically detected
command (or specify its location if the auto-detection fails to find it).
.. variable:: CPACK_PKGBUILD_IDENTITY_NAME
.. versionadded:: 3.8
Adds a digital signature to the resulting package.
.. variable:: CPACK_PKGBUILD_KEYCHAIN_PATH
.. versionadded:: 3.8
Specify a specific keychain to search for the signing identity.
.. variable:: CPACK_PREFLIGHT_<COMP>_SCRIPT
Full path to a file that will be used as the ``preinstall`` script for the
named ``<COMP>`` component's package, where ``<COMP>`` is the uppercased
component name. No ``preinstall`` script is added if this variable is not
defined for a given component.
.. variable:: CPACK_POSTFLIGHT_<COMP>_SCRIPT
Full path to a file that will be used as the ``postinstall`` script for the
named ``<COMP>`` component's package, where ``<COMP>`` is the uppercased
component name. No ``postinstall`` script is added if this variable is not
defined for a given component.
.. variable:: CPACK_PRODUCTBUILD_RESOURCES_DIR
.. versionadded:: 3.9
If specified the productbuild generator copies files from this directory
(including subdirectories) to the ``Resources`` directory. This is done
before the :variable:`CPACK_RESOURCE_FILE_WELCOME`,
:variable:`CPACK_RESOURCE_FILE_README`, and
:variable:`CPACK_RESOURCE_FILE_LICENSE` files are copied.
.. variable:: CPACK_PRODUCTBUILD_DOMAINS
.. versionadded:: 3.23
This option enables more granular control over where the product may be
installed. When it is set to true, a ``domains`` element of the following
form will be added to the productbuild Distribution XML:
.. code-block:: xml
<domains enable_anywhere="true" enable_currentUserHome="false" enable_localSystem="true"/>
The default values are as shown above, but can be overridden with
:variable:`CPACK_PRODUCTBUILD_DOMAINS_ANYWHERE`,
:variable:`CPACK_PRODUCTBUILD_DOMAINS_USER`, and
:variable:`CPACK_PRODUCTBUILD_DOMAINS_ROOT`.
.. variable:: CPACK_PRODUCTBUILD_DOMAINS_ANYWHERE
.. versionadded:: 3.23
May be used to override the ``enable_anywhere`` attribute in the ``domains``
element of the Distribution XML. When set to true, the product can be
installed at the root of any volume, including non-system volumes.
:variable:`CPACK_PRODUCTBUILD_DOMAINS` must be set to true for this variable
to have any effect.
.. variable:: CPACK_PRODUCTBUILD_DOMAINS_USER
.. versionadded:: 3.23
May be used to override the ``enable_currentUserHome`` attribute in the
``domains`` element of the Distribution XML. When set to true, the product
can be installed into the current user's home directory. Note that when
installing into the user's home directory, the following additional
requirements will apply:
* The installer may not write outside the user's home directory.
* The install will be performed as the current user rather than as ``root``.
This may have ramifications for :variable:`CPACK_PREFLIGHT_<COMP>_SCRIPT`
and :variable:`CPACK_POSTFLIGHT_<COMP>_SCRIPT`.
* Administrative privileges will not be needed to perform the install.
:variable:`CPACK_PRODUCTBUILD_DOMAINS` must be set to true for this variable
to have any effect.
.. variable:: CPACK_PRODUCTBUILD_DOMAINS_ROOT
.. versionadded:: 3.23
May be used to override the ``enable_localSystem`` attribute in the
``domains`` element of the Distribution XML. When set to true, the product
can be installed in the root directory. This should normally be set to true
unless the product should only be installed to the user's home directory.
:variable:`CPACK_PRODUCTBUILD_DOMAINS` must be set to true for this variable
to have any effect.
Background Image
""""""""""""""""
.. versionadded:: 3.17
This group of variables controls the background image of the generated
installer.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND
Adds a background to Distribution XML if specified. The value contains the
path to image in ``Resources`` directory.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND_ALIGNMENT
Adds an ``alignment`` attribute to the background in Distribution XML.
Refer to Apple documentation for valid values.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND_SCALING
Adds a ``scaling`` attribute to the background in Distribution XML.
Refer to Apple documentation for valid values.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND_MIME_TYPE
Adds a ``mime-type`` attribute to the background in Distribution XML.
The option contains MIME type of an image.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND_UTI
Adds an ``uti`` attribute to the background in Distribution XML.
The option contains UTI type of an image.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA
Adds a background for the Dark Aqua theme to Distribution XML if
specified. The value contains the path to image in ``Resources``
directory.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA_ALIGNMENT
Does the same as :variable:`CPACK_PRODUCTBUILD_BACKGROUND_ALIGNMENT` option,
but for the dark theme.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA_SCALING
Does the same as :variable:`CPACK_PRODUCTBUILD_BACKGROUND_SCALING` option,
but for the dark theme.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA_MIME_TYPE
Does the same as :variable:`CPACK_PRODUCTBUILD_BACKGROUND_MIME_TYPE` option,
but for the dark theme.
.. variable:: CPACK_PRODUCTBUILD_BACKGROUND_DARKAQUA_UTI
Does the same as :variable:`CPACK_PRODUCTBUILD_BACKGROUND_UTI` option,
but for the dark theme.
Distribution XML Template
^^^^^^^^^^^^^^^^^^^^^^^^^
CPack uses a template file to generate the ``distribution.dist`` file used
internally by this package generator. Ordinarily, CMake provides the template
file, but projects may supply their own by placing a file called
``CPack.distribution.dist.in`` in one of the directories listed in the
:variable:`CMAKE_MODULE_PATH` variable. CPack will then pick up the project's
template file instead of using its own.
The ``distribution.dist`` file is generated by performing substitutions
similar to the :command:`configure_file` command. Any variable set when
CPack runs will be available for substitution using the usual ``@...@``
form. The following variables are also set internally and made available for
substitution:
``CPACK_RESOURCE_FILE_LICENSE_NOPATH``
Same as :variable:`CPACK_RESOURCE_FILE_LICENSE` except without the path.
The named file will be available in the same directory as the generated
``distribution.dist`` file.
``CPACK_RESOURCE_FILE_README_NOPATH``
Same as :variable:`CPACK_RESOURCE_FILE_README` except without the path.
The named file will be available in the same directory as the generated
``distribution.dist`` file.
``CPACK_RESOURCE_FILE_WELCOME_NOPATH``
Same as :variable:`CPACK_RESOURCE_FILE_WELCOME` except without the path.
The named file will be available in the same directory as the generated
``distribution.dist`` file.
``CPACK_APPLE_PKG_INSTALLER_CONTENT``
.. versionadded:: 3.23
This contains all the XML elements that specify installer-wide options
(including domain details), default backgrounds and the choices outline.
``CPACK_PACKAGEMAKER_CHOICES``
.. deprecated:: 3.23
This contains only the XML elements that specify the default backgrounds
and the choices outline. It does not include the installer-wide options or
any domain details. Use ``CPACK_APPLE_PKG_INSTALLER_CONTENT`` instead.

CPack WIX Generator
-------------------
CPack WIX generator specific options
.. versionadded:: 3.7
Support :variable:`CPACK_COMPONENT_<compName>_DISABLED` variable.
Variables specific to CPack WIX generator
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^
The following variables are specific to the installers built on
Windows using WiX.
.. variable:: CPACK_WIX_UPGRADE_GUID
Upgrade GUID (``Product/@UpgradeCode``)
Will be automatically generated unless explicitly provided.
It should be explicitly set to a constant generated globally unique
identifier (GUID) to allow your installers to replace existing
installations that use the same GUID.
You may for example explicitly set this variable in your
CMakeLists.txt to the value that has been generated per default. You
should not use GUIDs that you did not generate yourself or which may
belong to other projects.
A GUID shall have the following fixed length syntax::
XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
(each X represents an uppercase hexadecimal digit)
.. variable:: CPACK_WIX_PRODUCT_GUID
Product GUID (``Product/@Id``)
Will be automatically generated unless explicitly provided.
If explicitly provided this will set the Product Id of your installer.
The installer will abort if it detects a pre-existing installation that
uses the same GUID.
The GUID shall use the syntax described for CPACK_WIX_UPGRADE_GUID.
.. variable:: CPACK_WIX_LICENSE_RTF
RTF License File
If CPACK_RESOURCE_FILE_LICENSE has an .rtf extension it is used as-is.
If CPACK_RESOURCE_FILE_LICENSE has an .txt extension it is implicitly
converted to RTF by the WIX Generator.
The expected encoding of the .txt file is UTF-8.
With CPACK_WIX_LICENSE_RTF you can override the license file used by the
WIX Generator in case CPACK_RESOURCE_FILE_LICENSE is in an unsupported
format or the .txt -> .rtf conversion does not work as expected.
.. variable:: CPACK_WIX_PRODUCT_ICON
The Icon shown next to the program name in Add/Remove programs.
If set, this icon is used in place of the default icon.
.. variable:: CPACK_WIX_UI_REF
This variable allows you to override the Id of the ``<UIRef>`` element
in the WiX template.
The default is ``WixUI_InstallDir`` in case no CPack components have
been defined and ``WixUI_FeatureTree`` otherwise.
.. variable:: CPACK_WIX_UI_BANNER
The bitmap will appear at the top of all installer pages other than the
welcome and completion dialogs.
If set, this image will replace the default banner image.
This image must be 493 by 58 pixels.
.. variable:: CPACK_WIX_UI_DIALOG
Background bitmap used on the welcome and completion dialogs.
If this variable is set, the installer will replace the default dialog
image.
This image must be 493 by 312 pixels.
.. variable:: CPACK_WIX_PROGRAM_MENU_FOLDER
Start menu folder name for launcher.
If this variable is not set, it will be initialized with CPACK_PACKAGE_NAME
.. versionadded:: 3.16
If this variable is set to ``.``, then application shortcuts will be
created directly in the start menu and the uninstaller shortcut will be
omitted.
.. variable:: CPACK_WIX_CULTURES
Language(s) of the installer
Languages are compiled into the WixUI extension library. To use them,
simply provide the name of the culture. If you specify more than one
culture identifier in a comma or semicolon delimited list, the first one
that is found will be used. You can find a list of supported languages at:
https://wixtoolset.org/docs/v3/wixui/wixui_localization/
.. variable:: CPACK_WIX_TEMPLATE
Template file for WiX generation
If this variable is set, the specified template will be used to generate
the WiX wxs file. This should be used if further customization of the
output is required.
If this variable is not set, the default MSI template included with CMake
will be used.
.. variable:: CPACK_WIX_PATCH_FILE
Optional list of XML files with fragments to be inserted into
generated WiX sources.
.. versionadded:: 3.5
Support listing multiple patch files.
This optional variable can be used to specify an XML file that the
WIX generator will use to inject fragments into its generated
source files.
Patch files understood by the CPack WIX generator
roughly follow this RELAX NG compact schema:
.. code-block:: none
start = CPackWiXPatch
CPackWiXPatch = element CPackWiXPatch { CPackWiXFragment* }
CPackWiXFragment = element CPackWiXFragment
{
attribute Id { string },
fragmentContent*
}
fragmentContent = element * - CPackWiXFragment
{
(attribute * { text } | text | fragmentContent)*
}
Currently fragments can be injected into most
Component, File, Directory and Feature elements.
.. versionadded:: 3.3
The following additional special Ids can be used:
* ``#PRODUCT`` for the ``<Product>`` element.
* ``#PRODUCTFEATURE`` for the root ``<Feature>`` element.
.. versionadded:: 3.7
Support patching arbitrary ``<Feature>`` elements.
.. versionadded:: 3.9
Allow setting additional attributes.
The following example illustrates how this works.
Given that the WIX generator creates the following XML element:
.. code-block:: xml
<Component Id="CM_CP_applications.bin.my_libapp.exe" Guid="*"/>
The following XML patch file may be used to inject an Environment element
into it:
.. code-block:: xml
<CPackWiXPatch>
<CPackWiXFragment Id="CM_CP_applications.bin.my_libapp.exe">
<Environment Id="MyEnvironment" Action="set"
Name="MyVariableName" Value="MyVariableValue"/>
</CPackWiXFragment>
</CPackWiXPatch>
.. variable:: CPACK_WIX_EXTRA_SOURCES
Extra WiX source files
This variable provides an optional list of extra WiX source files (.wxs)
that should be compiled and linked. The full path to source files is
required.
.. variable:: CPACK_WIX_EXTRA_OBJECTS
Extra WiX object files or libraries
This variable provides an optional list of extra WiX object (.wixobj)
and/or WiX library (.wixlib) files. The full path to objects and libraries
is required.
.. variable:: CPACK_WIX_EXTENSIONS
This variable provides a list of additional extensions for the WiX
tools light and candle.
.. variable:: CPACK_WIX_<TOOL>_EXTENSIONS
This is the tool specific version of CPACK_WIX_EXTENSIONS.
``<TOOL>`` can be either LIGHT or CANDLE.
.. variable:: CPACK_WIX_<TOOL>_EXTRA_FLAGS
This list variable allows you to pass additional
flags to the WiX tool ``<TOOL>``.
Use it at your own risk.
Future versions of CPack may generate flags which may be in conflict
with your own flags.
``<TOOL>`` can be either LIGHT or CANDLE.
.. variable:: CPACK_WIX_CMAKE_PACKAGE_REGISTRY
If this variable is set the generated installer will create
an entry in the windows registry key
``HKEY_LOCAL_MACHINE\Software\Kitware\CMake\Packages\<PackageName>``
The value for ``<PackageName>`` is provided by this variable.
Assuming you also install a CMake configuration file this will
allow other CMake projects to find your package with
the :command:`find_package` command.
.. variable:: CPACK_WIX_PROPERTY_<PROPERTY>
.. versionadded:: 3.1
This variable can be used to provide a value for
the Windows Installer property ``<PROPERTY>``
The following list contains some example properties that can be used to
customize information under
"Programs and Features" (also known as "Add or Remove Programs")
* ARPCOMMENTS - Comments
* ARPHELPLINK - Help and support information URL
* ARPURLINFOABOUT - General information URL
* ARPURLUPDATEINFO - Update information URL
* ARPHELPTELEPHONE - Help and support telephone number
* ARPSIZE - Size (in kilobytes) of the application
.. variable:: CPACK_WIX_ROOT_FEATURE_TITLE
.. versionadded:: 3.7
Sets the name of the root install feature in the WIX installer. Same as
CPACK_COMPONENT_<compName>_DISPLAY_NAME for components.
.. variable:: CPACK_WIX_ROOT_FEATURE_DESCRIPTION
.. versionadded:: 3.7
Sets the description of the root install feature in the WIX installer. Same as
CPACK_COMPONENT_<compName>_DESCRIPTION for components.
.. variable:: CPACK_WIX_SKIP_PROGRAM_FOLDER
.. versionadded:: 3.7
If this variable is set to true, the default install location
of the generated package will be CPACK_PACKAGE_INSTALL_DIRECTORY directly.
The install location will not be located relatively below
ProgramFiles or ProgramFiles64.
.. note::
Installers created with this feature do not take differences
between the system on which the installer is created
and the system on which the installer might be used into account.
It is therefore possible that the installer e.g. might try to install
onto a drive that is unavailable or unintended or a path that does not
follow the localization or convention of the system on which the
installation is performed.
.. variable:: CPACK_WIX_ROOT_FOLDER_ID
.. versionadded:: 3.9
This variable allows specification of a custom root folder ID.
The generator specific ``<64>`` token can be used for
folder IDs that come in 32-bit and 64-bit variants.
In 32-bit builds the token will expand empty while in 64-bit builds
it will expand to ``64``.
When unset generated installers will default installing to
``ProgramFiles<64>Folder``.
.. variable:: CPACK_WIX_ROOT
This variable can optionally be set to the root directory
of a custom WiX Toolset installation.
When unspecified CPack will try to locate a WiX Toolset
installation via the ``WIX`` environment variable instead.
.. variable:: CPACK_WIX_CUSTOM_XMLNS
.. versionadded:: 3.19
This variable provides a list of custom namespace declarations that are necessary
for using WiX extensions. Each declaration should be in the form name=url, where
name is the plain namespace without the usual xmlns: prefix and url is an unquoted
namespace url. A list of commonly known WiX schemata can be found here:
https://wixtoolset.org/docs/v3/xsd/
.. variable:: CPACK_WIX_SKIP_WIX_UI_EXTENSION
.. versionadded:: 3.23
If this variable is set then the inclusion of WixUIExtensions is skipped,
i.e. the ``-ext "WixUIExtension"`` command line is not included during
the execution of the WiX light tool.
.. variable:: CPACK_WIX_ARCHITECTURE
.. versionadded:: 3.24
This variable can be optionally set to specify the target architecture
of the installer. May for example be set to ``x64`` or ``arm64``.
When unspecified, CPack will default to ``x64`` or ``x86``.
