HIPHOSTCXX

.. versionadded:: 3.28

.. include:: include/ENV_VAR.rst

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 :variable:CMAKE_HIP_HOST_COMPILER <CMAKE_<LANG>_HOST_COMPILER>.

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

.. note::

Ignored when using :ref:Visual Studio Generators.
