Hi,  I was just about to do the same thing :)  However, yesterday, I 
came across some Qt documentation saying that the .prl files are of an 
internal format and Trolltech reserves the right to change the format 
whenever they want.
So, instead, I was going to read the mkspecs/qconfig.pri file to get the 
Qt configuration options (x11sm, freetype, xrandr, xinerama, etc...).  
Based on that, do some FIND_LIBRARY calls using library paths specified 
by qmake.

Does that sound like a better approach?
