Which version of CMake are you using?
Which set of CPack generator do you want to work with?

Multiple installer on the same tree is not really handled yet unless
you use multi-file component-aware installers
(ZIP, TGZ and other archive generators, RPM and DEB).

You can find more information about that here
http://www.cmake.org/Wiki/CMake:Component_Install_With_CPack

Now you scheme is more like the feature request described here:
http://public.kitware.com/Bug/view.php?id=11808

Have a look at that this thread too:
http://www.cmake.org/pipermail/cmake/2011-February/043075.html

So basically CPack does not currently support multi-package besides
the component things. If you want to join the effort to make it happen
please do so by throwing idea (on the mailing list or tracker)
and/or patch on the bug tracker.
