- CXX
- ---
- Preferred executable for compiling ``CXX`` language files. Will only be used by
- CMake on the first configuration to determine ``CXX`` compiler, after which the
- value for ``CXX`` is stored in the cache as
- :variable:`CMAKE_CXX_COMPILER <CMAKE_<LANG>_COMPILER>`. For any configuration
- run (including the first), the environment variable will be ignored if the
- :variable:`CMAKE_CXX_COMPILER <CMAKE_<LANG>_COMPILER>` variable is defined.
