title: Ubuntu16.04 run pcl in sublime text3, "fatal error: usr/include/pcl-1.7/pcl/point_types.h: No such file or directory"
body: <p>I am new to C++ and <code>pcl</code>. I use Ubuntu 16.04. I just want to try <code>pcl</code> <code>PFH</code> estimation. And I need to use two files:<code>point_types.h</code> and <code>features/pfh.h</code>.
  I included them at the top of my <code>.cpp</code> file:</p>
  
  <pre><code>"include usr/include/pcl-1.7/pcl/point_types.h"
  "include usr/include/pcl-1.7/pcl/features/pfh.h"
  </code></pre>
  
  <p>There is an error fatal error:</p>
  
  <blockquote>
    <p>usr/include/pcl-1.7/pcl/point_types.h: No such file or directory</p>
  </blockquote>
  
  <p>Why is that?
  Very grateful!</p>
