[CMake] linking error after upgrading to snow leopard

[Michael Jackson]

You are not specifying the libraries that contain those symbols.  
Looking at your link line you are missing at least the Qt libraries/ 
Frameworks and maybe some others.

If the arch were incorrect the linker would explicitly tell you that  
the libraries you are trying to link against is the wrong arch. Since  
I don't see that error I am assuming that you have forgotten to list  
the libraries that contain those symbols in a  
"target_link_libraries()" command.
