rez-pip PyQt5 on windows fails to add necessary paths to comands()

[Vochsel]

Unsure where this breaks, or who to send this too, but running:

rez-pip --python-version 3.7 -i PyQt5

Results in

qt.qpa.plugin: Could not find the Qt platform plugin "windows" in ""
This application failed to start because no Qt platform plugin could be initialized. Reinstalling the application may fix this problem.

unless the following two paths are added to the commands() of PyQt5_Qt5 package

env.PATH.append('{root}/python/PyQt5/Qt5/bin')
env.QT_PLUGIN_PATH.set('{root}/python/PyQt5/Qt5/plugins')

Cheers!
