pyqt5 is ancient at 5.5.1. This needs upgrading to 5.7.0 or 5.7.1.

ECM now has a magic macro which allows frameworks to generate bindings via sip/pyqt. This does however require the pyqt5 sips to be compatible with the Qt versions, since we have 5.5.1 it is only compatible with up to 5.5.1 though.

This is blocking kitemmodels building with PythonModuleGeneration (ecm magic) which in turn prevents it from generating bindings.

Also needs:

• sip4 (built)
• qtwebkit 5.7 (wip, community release, we were at 5.6 official release)
