Why is CMAKE_CUDA_ARCHITECTURES not enough #576
Description
In all host-configs we set both CMAKE_CUDA_ARCHITECTURES and add the -arch flag manually to the CMAKE_CUDA_FLAGS. Why is does this seem to be necessary? Is it possibly our reliance on the old FindCUDA, which is soon to be removed?
Does this flag need to be set if CMAKE_CUDA_ARCHITECTURES is set?
