[QGIS-Developer] QGIS master build on Ubuntu 16.04 with python support

[Theuns Heydenrych]

HI Jorge, thank you for the reply.
My out for dpkg -l | grep pyqt5 | awk '{print $2}'  is:

pyqt5-dev
pyqt5-dev-tools
pyqt5.qsci-dev
python-pyqt5
python-pyqt5.qsci
python3-pyqt5
python3-pyqt5.qsci
python3-pyqt5.qtsql
python3-pyqt5.qtsvg

My WITH_QTWEBKIT is set to false.

Regards
Theuns Heydenrych
