Export include paths to CUDAFLAGS environment variable #18

Closed carterbox closed 1 year ago

carterbox commented 1 year ago

Solution to issue cannot be found in the documentation.

Issue

In addition to CFLAGS and CXXFLAGS, the activation script should also export CUDAFLAGS which is the environment variable checked by recent versions of CMAKE to add flags nvcc calls [1]. Something like:

export CUDAFLAGS="${CUDAFLAGS} ${CUDA_CFLAGS}"

CFLAGS and CXXFLAGS may not be applied when nvcc compiler is compiling .cu files, but external CUDA library headers are still needed. CMake adds CUDAFLAGS (CMAKE_CUDA_FLAGS) to these calls. I'm not sure if the linking flags are also needed.

Thanks for filing @carterbox! I ran into this issue as well. I can help file a PR tomorrow, unless someone else has bandwidth to do so first.
