kdoctools

[Treeve Jelbert]

I build all of kf5 as standalone modules

kdoctools is now required when building kdewidgets, but the build fails

FAILED: cd /usr/src/kdewidgets-5.x/build/docs/makekdewidgets &&

kdoctools installs files to /opt/qt5/share/ksgmltools2/customization whereas 
kdelibs4 uses /opt/qt4/share/apps/ksgmltools2/customization

is the problem due to the extra apps directory?

is it possible to make the dependency on kdoctools optional?
