Getting error: Unknown module(s) in QT: webkitwidgets in QT 5.2.1 in Ubutu 12.04

I have built Qt 5 libs from source into Ubuntu 12.04 and made a Qt test app. In .pro file I have written QT += core gui webkitwidgets to use Qwebview in my test project.

But when I run qmake into Qt creator then it gives me error: Unknown module(s) in QT: webkitwidgets. I have also installed libqt5webkit5-dev package into my machine but still issue is not fixed.

I think webkit or webkitwidgets module is not build by source when I built Qt 5 libs from source In Ubutnu 12.04.

So how can I build qtwebkit or webkitwdgtes module from source or anybody who has idea about the issue then please let me know.

Thanks

May have something to do with webkitwidgets and webkit both being deprecated in Qt5? I read the other day that we should be using Qt WebEngine now
