using cudarray with strictly CPU

This library is a dependency for another library I want to use. I am curious if I can install this library to strictly use CPU.

If so, do I simply not set CUDA_PREFIX and set CUDNN_ENABLED=0 and only run "python setup.py --without-cuda install"? I need nvcc (from nvidia) if I am to do "make && make install".

Thanks for your time.

Cheers,
