An update. We used chroot from Archlinux and repos which provides a patched ANGLE, as seen here <https://github.com/edubart/archlibs/blob/master/mingw-w64/mingw-w64-angleproject/angleproject-fix-mingw-compatibility.patch#L51>, and it worked like a charm. We were able to compile qnanopainter and deploy it via qtwindeploy to a Windows host. Not sure if this rings some bells but just thought it was worth mentioning.
