Missing Qt module requirement in QQuickStyle class description

The example in the QQuickStyle reference does not compile out of the box: fatal error: QQuickStyle: No such file or directory.

To make it compile one has to add the module quickcontrols2 to the QT qmake variable.

I would be nice to have a hint in the reference of QQuickStyle about the required modules, like it is done for other widgets (for example QWidget)
