I have several Qt3 programs that I have put in a "Qt3" directory.
I want too write a new program in a "Qt4" directory. I am not shure how to set it up so that when I am editing a program in the "Qt3" directory I am using the correct librarys and qmake. ("/usr/share/qt3/..." directory)
The same goes for when I am working with a program in the "Qt4" directory. ("/usr/local/Trolltech/....") directory.

Any help would be appreciated.
