Qt is not build with 64 Bit and I use the same Qt Versions in multiple 
projects, so I doubt that that is the reason.
The thing mainly is, that mainwindow.cpp has a class in the ui called 
QCameraWidget, which is derived from QCameraImage.
The error thus appears in the base class. QCameraWidget and QCameraImage 
both are part of a DLL, which is loaded in the example where 
mainwindow.cpp is placed.
