CUDACXX — CMake 3.17.3 Documentation

# CUDACXX

This is a CMake Environment Variable. Its initial value is taken from the calling process environment.

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