[CMake] Mac application bundles & resources

[Matthew J Smith]

Hi everyone,

I've been approached to get a Mac application bundle built for the  
Speedcrunch calculator app (speedcrunch.digitalfanatics.org).  The  
app uses Qt 4 and is normally built using qmake, but the developers  
have started using CMake, which for the X11 install model (binaries  
in /usr/bin, resources in /usr/share) works fine.  However, although  
I can get CMake to build an application bundle, I can't find any  
instructions as to how to get the resources to install in the  
Resources directory within the bundle.

Does CMake even have this feature, and if so, can anyone tell me how  
to do this?  I'm using version 2.4.3.  I've attached my CMakeLists.txt.
