But in my eyes backporting these commits doesn't make too much sense, as master is currently quite stable and the latest 0.19 build is working with qtwebengine... Also I think if you want to work on a bundle from conda packages for windows using latest master makes more sense (weekly builds from freecad/label/dev)
So:
doesn't look that obvious anymore . So I will stay with qt5.6 for 0.18.3.
