Hi everyone,
I was wondering if someone is already working on Clang/CUDA support for the FindCUDA module. With clang 3.8 the --cuda-arch and --cuda-path directives allow to compile .cu files as an alternative to nvcc. Maybe we could just specify a steering variable such as set(CUDA_COMPILE_CHAIN "clang") set(CUDA_COMPILE_CHAIN "nvcc") before find_package(CUDA) to steer it (and of course adding the implementation). Alternatively, CUDA_HOST_COMPILER and adding CUDA_DEVICE_COMPILER (or reusing the advanced CUDA_NVCC_EXECUTABLE) might also be a way to go. Currently, you still need to have the CUDA toolkit from Nvidia installed to compile .cu files to ptx with clang, so I guess my question is really just about replacing nvcc and it's options with clang (using different options). What do you think?
