[CMake] Linking against OS X Frameworks

[ML]

OK All, I tried setting CFLAGS and CXXFLAGS on the command-line and  
nothing

I did

[jtsm at Jason-T-Slack-Moehrles-MacBook-Pro ~/Checkout/Universal GUI]$  
CFLAGS="-arch i386"
[jtsm at Jason-T-Slack-Moehrles-MacBook-Pro ~/Checkout/Universal GUI]$  
CXXFLAGS="-arch i386"
[jtsm at Jason-T-Slack-Moehrles-MacBook-Pro ~/Checkout/Universal GUI]$  
cmake -CinitialCache.cmake  .
loading initial cache file initialCache.cmake
-- Configuring done

[jtsm at Jason-T-Slack-Moehrles-MacBook-Pro ~/Checkout/Universal GUI]$ make

bit not supported

Still nothing. I am at a complete lose now as to what to do.

Does anyone have a clue? Weird I am the only one going through this...
