[Rtk-users] building CUDA

[Simon Rit]

That's more complicated. First, CUDA_HAVE_GPU is normally turned on
automatically but maybe it's been turned off due to the problem you're
encountering now.
The problem you have is probably not specific to RTK, we don't develop
FindCUDA.cmake. I quickly checked FindCUDA.cmake and there if an
option CUDA_BUILD_CUBIN, maybe turn it off?
If I were you, I'd try to create a small separate project with
has_cuda_gpu.c and check whether it compiles. If it doesn't, try the
cmake mailing list.
