Building from source with CUDA 9.1 #76

I tried to build kmcuda from source with: cmake -DCMAKE_BUILD_TYPE=Release -D CUDA_ARCH=91 -DCUDA_TOOLKIT_ROOT_DIR=/usr/local/cuda-9.1 . && make

but I am constantly getting an error:

How can I fix it?

No-no, CUDA_ARCH is the compute capability of your device. https://en.wikipedia.org/wiki/CUDA#GPUs_supported
