| CUDAHOSTCXX |
| ----------- |
| |
| Preferred executable for compiling host code when compiling ``CUDA`` |
| language files. Will only be used by CMake on the first configuration to |
| determine ``CUDA`` host compiler, after which the value for ``CUDAHOSTCXX`` is |
| stored in the cache as :variable:`CMAKE_CUDA_HOST_COMPILER`. For any |
| configuration run (including the first), the environment variable will be |
| ignored if the :variable:`CMAKE_CUDA_HOST_COMPILER` variable is defined. |
| |
| This environment variable is primarily meant for use with projects that |
| enable ``CUDA`` as a first-class language. The :module:`FindCUDA` |
| module will also use it to initialize its ``CUDA_HOST_COMPILER`` setting. |
