HIPHOSTCXX — CMake 4.1.4 Documentation

# HIPHOSTCXX

Added in version 3.28.

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

Preferred executable for compiling host code when compiling `HIP` language files with the NVIDIA CUDA Compiler. Will only be used by CMake on the first configuration to determine `HIP` host compiler, after which the value for `HIPHOSTCXX` is stored in the cache as `CMAKE_HIP_HOST_COMPILER`.

This environment variable is primarily meant for use with projects that enable `HIP` as a first-class language.

Note

Ignored when using Visual Studio Generators.
