The ExternalProject module has long used the generator-specific
placeholder in the `${CMAKE_CFG_INTDIR}` variable to express per-config
stamp file paths in multi-config generators. Now that most generators
support generator expressions in custom command outputs, we can use
the `$<CONFIG>` genex instead.
In particular, this fixes cross-config `BUILD_BYPRODUCTS` with the Ninja
Multi-Config generator.
Fixes: #23595
CMake Tests Directory ********************* This directory contains the CMake test suite. See also the `CMake Source Code Guide`_. .. _`CMake Source Code Guide`: ../Help/dev/source.rst Many tests exist as immediate subdirectories, but some tests are organized as follows. * ``CMakeLib/``: Source code, used for tests, that links to the ``CMakeLib`` library defined over in ``Source/``. * ``CMakeOnly/``: Deprecated. Tests that run CMake to generate a project but not build it. Superseded by ``Tests/RunCMake/``. * ``Find*/``: Tests for specific find modules that can only be run on machines with the corresponding packages installed. They are enabled in ``CMakeLists.txt`` by undocumented options used on CI builds. * ``Module/``: Tests for specific CMake modules. * ``RunCMake/``: Tests that run CMake and/or other tools while precisely checking their return code and stdout/stderr content. Useful for testing error cases and diagnostic output.
