title: make emacs cedet semantic look for include directories
body: <p>Cedet is a nice tool suite but in default configuration it has some difficulty locating included files.</p>
  
  <p>I would like to make it look for a directory called include/ in each parent directory and get the file from there.</p>
  
  <p>for examplme a file <code>/home/fakedrake/my-project/some-thing/something-else/file.c</code> has <code>#include "file.h"</code>
  file.h is  in some-thing/file.h but cedet fails to locate it</p>
  
  <p>What would be awesome would be to make cedet look for file.h to create completions in directories</p>
  
  <pre><code>/home/fakedrake/my-project/some-thing/include/
  /home/fakedrake/my-project/include/
  </code></pre>
  
  <p>( and i could live with it if it tried to look for </p>
  
  <pre><code>/include/
  /home/include/
  /home/fakedrake/include/ 
  </code></pre>
  
  <p>)</p>
