Linking the CUDA version with CMake

[ovysotska]

I tried to use the precompiled version of <liboverfeat.a> from my code and it worked out.
However, I would like to have feature extraction faster and I tried to do the linking procedure for the CUDA version liboverfeat_cuda.a as well.

Unfortunately, it seems that the THCudaTensor.hpp needs THC.h to able to use libTHC.a.

So the question: should there also be THC.h file provided to link to the CUDA version? Or it could be done in any other way?

Thanks!
