[PyQt] Dev setup on windows

[Patrick Stinson]

Another roadblock in PyQt5 on “nmake install” (after hacking configure scripts Re: previous emails). It appears the path separators are mangled and also the debug_suffix is not applied.

Just looking for how you do it without running into these problems. Thanks!
