Please have a look at the Superbuild CMakeLists.txt I did for kdegraphics.
It can build all-in-one, but then internally each repository is included as a 
cmake "ExternalProject", i.e. it still builds as if it was independent (but 
controlled by the super-CMakeLists.txt):

And you can not only do that, you could also write such a super-CMakeLists.txt 
for the whole KDE SC, enable only e.g. potato guy, and it will iteratively 
tell you which additional subprojects you need to enable to have all 
dependencies satisfied.
Then you can build exactly that.
Or you could create a source package consisting of exactly those subprojects 
needed for potato guy.

I haven't done this for whole KDE SC yet, but I tested it on kdegraphics and 
kdesupport so far and it works.

I'm basically waiting for more feedback especially from packagers.
