I deleted all my build files to rebuild against new kde-qt master yesterday.

PRECISIONS please read

PS: Andreas, I know what I do and if I say there is an error then I built 
clean and you should take my word ( as I am a fellow KDE developer and I take 
my responsabilies and I usually know what I am doing). This goes for Patrick 
as well. I am the kdeedu coordinator and as such I need to ensure it builds on 
all platforms, Linux included and when I say it does not build, then it does 
not for me (I test!), clean (here it does not link properly). It was also 
reported to me by other KDE people, pointing to my responsability of this 
module maintainer. I reversed Patrick's commit in trunk so trunk is OK but I 
don't know about beta 1 tag.

This is when   ${QT_QTSCRIPTTOOLS_LIBRARY} is in the CMakeLists.txt and when I 
build with
QtScriptTools instead 
it's all OK (in trunk) (again, I did not check the beta 1 release tag and I 
just wondered if it was OK or not).

Andreas, have a go with ${QT_QTSCRIPTTOOLS_LIBRARY} and tell me what you get, 
thanks
