title: make pycaffe -> "fatal error: cublas_v2.h: No such file or directory"
body: <p>I compiled <code>caffe</code> and I know trying to compile <code>pycaffe</code>. When I run <code>make pycaffe</code> in the <code>caffe</code> root folder, I get:</p>
  
  <pre><code>f@f-VirtualBox:~/caffe/caffe-master$ make pycaffe
  CXX src/caffe/layer_factory.cpp

  <p>How to fix that?</p>
