Yes, it's fairly easy to do with normal make but we've got a very  
large project that is configured via qmake for Mac, Windows and  
Linux.  It would be nice if we could do all we needed in qmake.  We  
might just resort to running a script to modify the makefile that's  
generated by qmake but if it's possible to do it in qmake then it  
would make life much easier.
