building pgadmin4 - Mailing list pgsql-hackers

I'm trying to build pgadmin4, out of curiosity.

I'm on a ubuntu 13.10 desktop vm.

I added qt webkitwidgets, and now I run into the next error, which doesn't seem to make much sense:
wbloos2@vm1:~/pgadmin4/runtime$ qmake
Project MESSAGE: Building for QT5+...
Project ERROR: Unknown module(s) in QT: quick

I haven't found the word "quick" in any of the code and there's no .qml file.

any clues?

Cheers,

WBL
