title: MOC file generation in VS2013
body: <p>I have a project generated from a .pro file. I cannot compile it because MOC files are not generated.</p>
  
  <ul>
  <li><code>Q_OBJECT</code> is used in headers for classes to be MOCed</li>
  <li><code>#pragma once</code> is used in headers for classes to be MOCed</li>
  </ul>
  
  <p>I put the verbosity to detailled, and I can see that moc is called on the right classes. Then, there is following error: <code>standard input(0): Note: No relevant classes found. No output generated.</code></p>
  
  <p>Finally, compiler cannot link moc files, and build is failing:</p>
  
  <pre><code>8&gt;  moc_myClass.cpp
  8&gt;c1xx : fatal error C1083: Cannot open source file: 
  'D:\Things\\L_build\Stuff\moc\moc_myClass.cpp': No such file or directory
  </code></pre>
  
  <p>Any clue?</p>
