The error is this:
> ld warning: in /Library/Frameworks//QtGui.framework/QtGui, file is not of required architecture
Your program is compiling for one architecture but the Qt libs are compiled for another. My guess is that you are default compiling for 32 bit (since that is the default under 10.5.8) but the Qt 4.8.1 libraries are 64 bit. You can check this but issuing the following command:
file /Library/Frameworks//QtGui.framework/QtGui
and the output will tell you what architectures are present in the library.
Then add the "x86_64" flag for the OS_X_ARCHITECTURES to your cmake cache using either ccmake or CMake-GUI.
Hope that helps
