Which version of CMake/CPack are you using?

More information about CPack RPM (and others) is there:

Yes probably,
CPack will package objects (FILE, TARGET, etc..) which are found
in INSTALL rules?
Do you have INSTALL statements in your CMakeLists.txt

Nope.
You won't get the dependency automatically (at least not with current CPack RPM)

You may look at BundleUtilities CMake module for that purpose, but
I don't know how far it can go.
