I've sent a link to this discussion and the build error to the Qt WebEngine 
people. You can reach them easily (during working hours) in the #qtwebengine 
channel on freenode IRC. They are definitely receptive to your input. And, 
FWIW, Simon and Allan are both still very close to the KDE project. Simon e.g. 
already created https://codereview.qt-project.org/#/c/103225/ based on your 
report. http://qt-project.org/wiki/QtWebEngineHowToTry lists all dependencies, 
and they have an open bug report about improving the build system as well.

So, tl;dr; they will improve this. And I hope you are not burnt by your past 
experiences with $whomever in the Qt eco system. It's a versatile bunch, and 
most of them are very open to suggestions from the outside and will try to 
help anyone, and KDE in particular, as fast as possible.
