The set of compile flags used for a target's C and C++ sources is based
on the linker language.  By default this is always the C++ flags if any
C++ sources appear in the target, and otherwise the C flags.  Therefore
we can define the `COMPILE_LANGUAGE` generator expression in
`INCLUDE_DIRECTORIES` to match the selected language.

This is not exactly the same as for other generators, but is the best VS
and Xcode can do.  It is also sufficient for many use cases since the
set of include directories for C and C++ is frequently similar but may
be distinct from those for other languages like CUDA.

Fixes: #17435

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  Superseded by ``Tests/RunCMake/``.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.
