title: Can't use QtQuick (QML) on Qt 5.7.1
body: <p>I use Qt 5.7.1 and Qt Creator 4.2.0 and I tried to use QtQuick.
  <strong>But I can't compile any QtQuick project.</strong></p>
  
  <p>Even when I try to just create a basic QtQuick Application and then compile it (<em>without any modification</em>), I have the following error:</p>
  
  <blockquote>
    <p>qrc:/main.qml:1 plugin cannot be loaded for module "QtQuick": Failed to extract plugin meta data from 'C:/Qt/Qt5.7.1/5.7/mingw53_32/qml/QtQuick.2/qtquick2plugind.dll'</p>
  </blockquote>
  
  <p>I checked and the dll exists. I also tried to compile in release mod.
  I also tried to run a Qt example (planet-qml) but I have the same error message.</p>
  
  <p>Strange thing is that <strong>it works on 5.5.0 Qt</strong> version.</p>
  
  <p>Does anyone have any idea of why this is not working?
  Thanks for your help and have a good day!</p>
