After being mired down in details of re-building OpenCV for Windows 7, my head is still "in the weeds", so I need to ask what are likely dumb questions to regain my bearings:
I have rebuilt OpenCV with MinGW32. But what exactly have I built: Win32 libraries?
If I now install the QT development environment, does it come with MinGW32 and do I need to re-build OpenCV with that development tool? If so, again, what am I building; something different from what I build before I installed QT?
