CUDAHOSTCXX — CMake 3.10.2 Documentation

# 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 `CMAKE_CUDA_HOST_COMPILER`. For any configuration run (including the first), the environment variable will be ignored if the `CMAKE_CUDA_HOST_COMPILER` variable is defined.
