[CMake] Can't link Qt libraries CMake 2.8.7 + OSX 10.5 + Qt 4.8.1

[Carlo Nicolini]

I've a very strange problem while trying to compile a the example provided
at

http://www.cmake.org/Wiki/images/2/25/QtTest-Package-Example.zip

System Informations:
Mac OSX 10.5.8

cmake version 2.8.7 installed from latest dmg package available
Qt 4.8.1 Installed from latest repositories

I issue the following commands in the QtTest-Package example
cmake .
make

I kept the original CMakeLists.txt unmodified but at last stage, the linker
can't find symbols and this is the output:

ld warning: in /Library/Frameworks//QtGui.framework/QtGui, file is not of
required architecture
ld warning: in /Library/Frameworks//QtCore.framework/QtCore, file is not of
required architecture

Trying to build the same example under QtCreator works smoothly, as well in
my system as in another Linux box.

What can be the error here?

Many thanks in advance
