No. At least not ... yet.
There is a bug report pending for that:
http://public.kitware.com/Bug/view.php?id=13176
and this one too:
http://public.kitware.com/Bug/view.php?id=12997

For the one which exists (and for any CPack generator) one should defined
CPACK_xxx vars before include(CPack) or inside CPACK_PROJECT_CONFIG_FILE
if one uses it.
see:
http://www.cmake.org/Wiki/CMake:CPackPackageGenerators#Overall_usage_.28common_to_all_generators.29

There is the multi-component inside CMake source but it is obviously
not enough for RPM (or DEB).

> The trivial single package rpm descriptions are useless for this...

Yes you are right.
Holidays are coming may be I'll get a chance to use some spare time
to tackle with the ever growing pile of requests for CPack[RPM]:

and set Category to CPack and refresh...
