HIPCXX

Added in version 3.21.

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

Preferred executable for compiling HIP language files. Will only be used by CMake on the first configuration to determine HIP compiler, after which the value for HIP is stored in the cache as CMAKE_HIP_COMPILER. For any configuration run (including the first), the environment variable will be ignored if the CMAKE_HIP_COMPILER variable is defined.
