[CMake] [OS X] example CMake file to create a Preference Pane?

[René J. V. Bertin]

Hi,

I'd like to experiment writing a Preference Pane for Qt-based apps. I'd prefer 
to use CMake instead of Xcode and wonder if someone can point me to an example 
CMake file that generates a proper .prefPane bundle? I'm not having much luck 
googling for one for now.

Thanks,
René
