Previously, we have been building our application for MacOS using Xcode, but I would like to switch to QtCreator. The switch to the new IDE was relatively painless, but I have noticed that compiling in QtCreator is significantly slower. Instead of finishing in 8 minutes in Xcode, it now takes 14 minutes to build the application in QtCreator. I have used Qt 4.7.4 with a x86 32 bit tool chain (gcc in QtCreator and clang in Xcode) for the comparison.

I bet you compare different compilers. By default Xcode uses clang, and QtCreator gcc 4.2, which is much slower.
Set up clang++ as C++ compiler, and it will be much faster.
