[vtkusers] [Snapshot-users] How to compile Qt-4.5.x for Mac OS X 10.5.5 to use 64-bits and Cocoa bindings

[Michael Jackson]

I think what they are doing is FORCING a Cocoa build if one selects a  
64 bit build of Qt. Just guessing but that does kinda make sense. You  
still could build Qt 4.5 with Carbon support for 32 Bit systems.

You will probably have to follow the flow of the code to get a better  
feel for the context that that bit of code is executed in.
