| CUDACXX |
| ------- |
| |
| .. versionadded:: 3.8 |
| |
| .. include:: ENV_VAR.txt |
| |
| Preferred executable for compiling ``CUDA`` language files. Will only be used by |
| CMake on the first configuration to determine ``CUDA`` compiler, after which the |
| value for ``CUDA`` is stored in the cache as |
| :variable:`CMAKE_CUDA_COMPILER <CMAKE_<LANG>_COMPILER>`. For any configuration |
| run (including the first), the environment variable will be ignored if the |
| :variable:`CMAKE_CUDA_COMPILER <CMAKE_<LANG>_COMPILER>` variable is defined. |
| |
| .. note:: |
| Options that are required to make the compiler work correctly can be included; |
| they can not be changed. |
