There would be two places to look.   As long as we are not talking about
umbrella frameworks it should not be too hard.  
Here is a thread about it on the cmake list: 
http://public.kitware.com/pipermail/cmake/2005-December/007736.html

To implement this, it would have to be done in two places:
1. the unix makefile generator.  cmLocalUnixMakefileGenerator.cxx
For a similar thing, you can see the support for Mac APP bundles
in cmake:

cmLocalUnixMakefileGenerator3::WriteExecutableRule

Look for MACOSX_BUNDLE

For a framework, it would be something similar, but in
cmLocalUnixMakefileGenerator3
::WriteSharedLibraryRule
