Neither tiff nor mng has a pkg-config .pc file. You probably have to do 
something specific to tell cmake that tiff depends on jpeg and mng 
depends on lcms. I guess you could also add .pc files for tiff and mng.

For Qt's qmake, I hacked src/gui/image/qmnghandler.pri to add -lcms.

I notice that QtGui.prl and the related .pc have -ljpeg before -ltiff. I 
think it's just good luck that this works. '-ljpeg' is there because 
QtGui depends directly on it, not because of -ltiff. I should probably 
fix this.
