[webkit-qt] I can not compile QtWebKit with Qt 4.8.1

[Renata Hodovan]

Hi Hertusz!

You can build the current WebKit with the latest Qt5 version only. For
this you can download qt5-tools from
https://github.com/ossy-szeged/qt5-tools. It contains a script and the
latest hash of the qt5 repository. Running build-qt5.sh with sudoer rights
will download and build the latest qt5 for you.
Then you have to set the QTDIR envrionment variable to
/usr/local/Trolltech/Qt5/Qt-5.0.0-r40. After this, hopefully you will be
able to build WebKit.

Regards,
Reni
