CUDAHOSTCXXΒΆ
Added in version 3.8.
This is a CMake Environment Variable. Its initial value is taken from the calling process environment.
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
CMAKE_CUDA_HOST_COMPILER.
This environment variable is preferred over
CMAKE_CUDA_HOST_COMPILER.
This environment variable is primarily meant for use with projects that
enable CUDA as a first-class language.
Note
Ignored when using Visual Studio Generators.
Added in version 3.13: The FindCUDA
module will use this variable to initialize its CUDA_HOST_COMPILER setting.
