[CMake] Architecture problem on OSX+Qt deployment

[Michael Jackson]

The "unknown load command" is because who ever built the Qt libraries did not set the Deployment Target to 10.5. Which is causing the failure. Also printed on the Download page for Qt (qt-project.org) is the following under the system requirements.

------
64-bit Apple Mac OS X 10.6 or later with xCode
------

So clearly from the Qt project page your system is NOT supported. You can either try to work with Qt 4.7.4 on OS X 10.5 OR upgrade your system to OS X 10.6.8. Your Choice but your current combination of Qt 4.8 and OS X 10.5 will NOT work together.
