[Qt-interest] configure.ac with Qt project

[Frank Lutz]

I do could fix the library problem. I do have installed libqtcore4
and not libqt4-core. Don't know why but nor it works.As operating system 
i use sidux (light debian).

Now i do also not get the error message "'%'-style pattern rules are a 
GNU make extension". But on make it will stop at this part
Makefile: *** missing separator
    moc $< -o $@
