Cautions on using windeployqt on Qt Quick Controls based applications

When packaging applications using windeployqt in Qt 5.5, you may experience the application doesn't show the interface because windeployqt doesn't recognize links to PrivateWidgets.

To solve the problem, copy qml\QtQuick\PrivateWidgetsfolder in Qt to respective location in deployment folder(e.g. deployment\QtQuick\PrivateWidgets).

Hope this helps those working with Qt Quick Controls.
