[CMake] CPack and install_name_tool on the Mac

[Karl Merkley]

Does CPack have any ability to help with the install_name_tool on the  
Mac?  Mac applications avoid DLL hell by creating an application  
bundle that is really a directory structure that includes the  
application, the resources, and the shared libraries used by the  
application.   My understanding is that the install_name_tool  
essentially modifies the RPATH of the distributed application so that  
it looks for the shared libraries in the bundle rather than some  
random location.   I have a script that I run to make this all work,  
but it has to be modified as libraries change.  Or, if I somehow  
forget to run this step the whole distribution is bad.   Does CPack  
help with this?

    Thanks,
          Karl
