When configured with --enable-isystem.
Was necessary to split QT_INCLUDES into QT_INCLUDES and
QT_MOC_INCLUDES because moc does not understand -isystem, e.g.:
Unknown options: isystem/usr/local/Cellar/qt/5.10.0_1/include/QtNetwork[...]
This does not convert all uses, but focuses on libraries which have triggered
warnings/errors when applying initial additional build checks: QT, Univalue, and Berkeley DB.
LevelDb requires additional measures as its code is compiled with the project warnings
via AM_CXXFLAGS.
Note -isystem should not be applied to /usr/include, see BITCOIN_SYSTEM_INCLUDE
for a helper to convert -I to -isystem with /usr/include excepted.
-Werror=documentation if isystem & werror are enabled.
And solve associated error:
