title: Since Qt3D says Linux is supported, how should I deal with absence of window.h on Linux?
body: <p>Qt3D has been officially supported by Qt 5.5. They say that <a href="http://doc.qt.io/qt-5/qt3d-index.html" rel="nofollow">Linux is supported</a>.  </p>
  
  <p>I choose an <a href="http://doc.qt.io/qt-5/qt3drenderer-assimp-example.html" rel="nofollow">assimp example</a>, and its <a href="http://doc.qt.io/qt-5/qt3drenderer-assimp-main-cpp.html" rel="nofollow">main.cpp</a> contains window.h .</p>
  
  <p>I am on Ubuntu 14.04.3. How am I supposed to compile this program?</p>
  
  <p><code>No such file or directory</code> is the error which I am receiving.</p>
