# This is the main entry function for creating a Qt module, that typically
# consists of a library, public header files, private header files and configurable
# features.
#
# A CMake target with the specified target parameter is created. If the current source
# directory has a configure.cmake file, then that is also processed for feature definition
# and testing. Any features defined as well as any features coming from dependencies to
# this module are imported into the scope of the calling feature.
#
# Target is without leading "Qt". So e.g. the "QtCore" module has the target "Core".
#
# Options:
#   NO_ADDITIONAL_TARGET_INFO
#     Don't generate a Qt6*AdditionalTargetInfo.cmake file.
#     The caller is responsible for creating one.
#
#   MODULE_INTERFACE_NAME
#     The custom name of the module interface. This name is used as a part of the include paths
#     associated with the module and other interface names. The default value is the target name.
#     If the INTERNAL_MODULE option is specified, MODULE_INTERFACE_NAME is not specified and the
#     target name ends with the suffix 'Private', the MODULE_INTERFACE_NAME value defaults to the
#     non-suffixed target name, e.g.:
#        For the SomeInternalModulePrivate target, the MODULE_INTERFACE_NAME will be
#        SomeInternalModule
#
#   HEADER_MODULE
#     Creates an interface library instead of following the Qt configuration default. Mutually
#     exclusive with STATIC.
#
#   STATIC
#     Creates a static library instead of following the Qt configuration default. Mutually
#     exclusive with HEADER_MODULE.
#
#   EXTERNAL_HEADERS
#     A explicit list of non qt headers (like 3rdparty) to be installed.
#     Note this option overrides install headers used as PUBLIC_HEADER by cmake install(TARGET)
#     otherwise set by syncqt.
#
#   EXTERNAL_HEADERS_DIR
#     A module directory with non qt headers (like 3rdparty) to be installed.
#     Note this option overrides install headers used as PUBLIC_HEADER by cmake install(TARGET)
#     otherwise set by syncqt.
#
#   PRIVATE_HEADER_FILTERS
#     The regular expressions that filter private header files out of target sources.
#     The value must use the following format 'regex1|regex2|regex3'.
#
#   QPA_HEADER_FILTERS
#     The regular expressions that filter QPA header files out of target sources.
#     The value must use the following format 'regex1|regex2|regex3'.
#
#   HEADER_SYNC_SOURCE_DIRECTORY
#     The source directory for header sync procedure. Header files outside this directory will be
#     ignored by syncqt. The specifying this directory allows to skip the parsing of the whole
#     CMAKE_CURRENT_SOURCE_DIR for the header files that needs to be synced and only parse the
#     single subdirectory, that meanwhile can be outside the CMAKE_CURRENT_SOURCE_DIR tree.

# Get a set of Qt module related values based on the target.

# preform values for the output variables. _qt_module_interface_name it's the basic name of module
# without "Qtfication" and the "Private" suffix if we speak about INTERNAL_MODULEs. Typical value of
# the _qt_module_interface_name is the provided to qt_internal_add_module ${target} name, e.g. Core.
# _qt_module_interface_name is used to preform all the include paths unless the
# _qt_module_include_name property is specified. _qt_module_include_name is legacy property that
# replaces the module name in include paths and has a higher priority than the
# _qt_module_interface_name property.
#
# When doing qt_internal_module_info(foo Core) this method will set the following variables in
# the caller's scope:
#  * foo with the value "QtCore"
#  * foo_versioned with the value "Qt6Core" (based on major Qt version)
#  * foo_upper with the value "CORE"
#  * foo_lower with the value "core"
#  * foo_include_name with the value"QtCore"
#    Usually the module name from ${foo} is used, but the name might be different if the
#    MODULE_INCLUDE_NAME argument is set when creating the module.
#  * foo_versioned_include_dir with the value "QtCore/6.2.0"
#  * foo_versioned_inner_include_dir with the value "QtCore/6.2.0/QtCore"
#  * foo_private_include_dir with the value "QtCore/6.2.0/QtCore/private"
#  * foo_qpa_include_dir with the value "QtCore/6.2.0/QtCore/qpa"
#  * foo_interface_name the interface name of the module stored in _qt_module_interface_name
#    property, e.g. Core.
#
# The function also sets a bunch of module include paths for the build and install interface.
# Variables that contains these paths start with foo_build_interface_ and foo_install_interface_
# accordingly.
# The following variables are set in the caller's scope:
#  * foo_<build|install>_interface_include_dir with
#    qtbase_build_dir/include/QtCore for build interface and
#    include/QtCore for install interface.
#  * foo_<build|install>_interface_versioned_include_dir with
#    qtbase_build_dir/include/QtCore/6.2.0 for build interface and
#    include/QtCore/6.2.0 for install interface.
#  * foo_<build|install>_versioned_inner_include_dir with
#    qtbase_build_dir/include/QtCore/6.2.0/QtCore for build interface and
#    include/QtCore/6.2.0/QtCore for install interface.
