Is there a reason why you are using C++ then? Maybe have a look at Python. Integration of 
and OpenCV is much easier there. There you basically need to pip install opencv-python and our python wheel, e.g. pip install "%CVB%Lib\Python\cvb-1.1-cp35.cp36.cp37-none-win_amd64.whl" (with maybe a --user option.
Edit: Qt is also supported by the way 
: pip install PySide2.
