title: Error building caffe - cannot find -lhdf5_hl
body: <p>I was following this guide to install caffe. I am using ubuntu 16.04 and installing caffe for cpu only(i don't have Nvidia gpu). 
  <a href="https://chunml.github.io/ChunML.github.io/project/Installing-Caffe-CPU-Only/" rel="nofollow noreferrer">https://chunml.github.io/ChunML.github.io/project/Installing-Caffe-CPU-Only/</a><br>
  But encountered the following error : </p>
  
  <pre><code>LD -o .build_release/lib/libcaffe.so.1.0.0
  /usr/bin/ld: cannot find -lhdf5_hl
  collect2: error: ld returned 1 exit status
  Makefile:572: recipe for target '.build_release/lib/libcaffe.so.1.0.0' 
  failed
  make: *** [.build_release/lib/libcaffe.so.1.0.0] Error 1
  </code></pre>
  
  <p>Can someone please help me figure out how to get past this? Thanks</p>
