title: Windeployqt deploys everything but exe file
body: <p>I am trying to deploy a QML application using</p>
  
  <pre><code>C:\Qt59\5.10.1\msvc2015_64\bin\windeployqt.exe --dir e:\deptest --qmldir e:\ais e:\build-ais-Desktop_Qt_5_10_1_MSVC2015_64bit2-Release\release\ais.exe
  </code></pre>
  
  <p>This copies all the needed files to e:\deptest, however the exe file I am calling windeployqt on is not being copied. If I copy it to the target folder manually I can run it just fine.</p>
  
  <p>Windeployqt finishes without error, however I am not quite sure whether this is expected behavior, or whether  am doing something wrong here.</p>
  
  <p>Do I have to copy the exe myself, or am I missing something?</p>
