As far as I can tell, the reason Qt5 Designer does not load custom PyQt5 widgets
is due to the 'stock' shared library
libpyqt5.so (which comes with PyQt5) not
being built for the correct combination of the Python and Qt versions. It seems
the only way to get around this is to build PyQt5 from source so we will have a
libpyqt5.so that is correct and will be able to load the custom widgets.
