title: make all fatal error when caffe is compiled
body: <p>I have installed OpenCV which shows version 3.0.2 when I write python commands. But when I try to run make all for caffe I am getting this output:</p>
  <pre><code>fatal error: opencv2/core/core.hpp: No such file or directory
   #include &lt;opencv2/core/core.hpp&gt;
            ^~~~~~~~~~~~~~~~~~~~~~~
  compilation terminated.
  Makefile:591: recipe for target '.build_release/src/caffe/util/io.o' failed
  make: *** [.build_release/src/caffe/util/io.o] Error 1
  </code></pre>
  <p>Anyone who can assist with what the issue I am facing might be here?</p>
