title: Resource compiling not invoked by qmake
body: <p>There is a way to automatically trigger recompilation of resource files when some of the original resource files (icons, text files, etc.) are changed?</p>
  
  <p>E.g. if I have a .pro file with</p>
  
  <pre><code>RESOURCES = something.qrc
  </code></pre>
  
  <p>and in the something.qrc file I have something like </p>
  
  <pre><code>   &lt;RCC&gt;
      &lt;qresource prefix="/localfile"&gt;
          &lt;file&gt;shaders/mytextfile.fs&lt;/file&gt;
      &lt;/qresource&gt;
     &lt;/RCC&gt;
  </code></pre>
  
  <p>If I change the mytextfile.fs file the generation of the qrc_something.cpp file is not triggered.</p>
