Logical target names must be globally unique.

|
|
Targets names created with :command:`add_executable`, :command:`add_library`, or
|
|
|
|
|
:command:`add_custom_target` are logical build target names. Logical target
|
2023-11-01 06:11:15 +08:00
|
|
|
names must be globally unique because:

|
::
|
|
|
|
|
|
|
|
|
|
- Unique names may be referenced unambiguously both in CMake
|
|
|
|
|
code and on make tool command lines.
|
|
|
|
|
- Logical names are used by Xcode and VS IDE generators
|
|
|
|
|
to produce meaningful project names for the targets.
|
|
|
|
|
|
|
|
|
|
The logical name of executable and library targets does not have to
|
|
|
|
|
correspond to the physical file names built. Consider using the
|
2023-11-01 06:20:22 +08:00
|
|
|
:prop_tgt:`OUTPUT_NAME` target property to create two targets with the same
|
2023-11-01 06:11:15 +08:00
|
|
|
physical name while keeping logical names distinct. Custom targets
|
|
|
|
|
must simply have globally unique names (unless one uses the global
|
2023-11-01 06:20:22 +08:00
|
|
|
property :prop_gbl:`ALLOW_DUPLICATE_CUSTOM_TARGETS` with a Makefiles generator).

the :command:`cmake_policy` command to set it to ``OLD`` or ``NEW`` explicitly.
