Received the follow error when building, this fixes it

I had this same issue. I don't know if it has any effect, but I added the library path instead of the specific file path: -DCMAKE_LIBRARY_PATH=/usr/local/cuda/lib64/stubs, and the build completed without errors.

I don't know which approach is optimal.

@Obeyed agree with you, changed it to the dir location instead of the file

I've create a pull request #60 that fixes the issue as recommended by @Obeyed in his comment from last March. Sorry if the additional request causes confusion - I wasn't sure how to attach the change to this one.
