| 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. |
