Preferred executable for compiling host code when compiling ``CUDA``
|
|
|
|
|
language files. Will only be used by CMake on the first configuration to
|
|
|
|
|
determine ``CUDA`` host compiler, after which the value for ``CUDAHOSTCXX`` is
|
|
|
|
|
stored in the cache as :variable:`CMAKE_CUDA_HOST_COMPILER`. For any
|
|
|
|
|
configuration run (including the first), the environment variable will be
|
|
|
|
|
ignored if the :variable:`CMAKE_CUDA_HOST_COMPILER` variable is defined.
|
|
|
|
|
|
|
|
|
|
This environment variable is primarily meant for use with projects that
|
|
|
|
|
enable ``CUDA`` as a first-class language.

Ignored when using :ref:`Visual Studio Generators`.

The :module:`FindCUDA`
|
|
|
|
|
module will use this variable to initialize its ``CUDA_HOST_COMPILER`` setting.
