[vtkusers] newbie compile question

[Mike Jackson]

Ok.. Here is a better way to do this. Delete the CMakeCache.txt from  
your build directory. (The directory that you are trying to build the  
Qt related stuff in. NOW, in your .bash_profile (or equivalent) set  
the 'QTDIR' environment variable to the root of the Qt4 installation,  
so that if you were to use ${QTDIR}/bin/qmake , qmake would actually  
execute. Source the new .bash_profile. Now run ccmake and see if the  
proper Qt is picked up.
