CMAKE_<LANG>_HOST_COMPILER_VERSION

New in version 3.31.

This variable is available when <LANG> is CUDA or HIP and CMAKE_<LANG>_COMPILER_ID is NVIDIA. It contains the version of the host compiler invoked by nvcc, either by default or as specified by CMAKE_<LANG>_HOST_COMPILER, in the same format as CMAKE_<LANG>_COMPILER_VERSION.
