I don't think so.
See e.g. http://public.kitware.com/Bug/view.php?id=8438.

Perhaps you could reverse it?
Since the default "install" and "package" targets depends on "all" per 
default have "all" build everything that is actually required for the 
install.

Then add a custom target (add_custom_target(subset)) and set up 
dependencies for it to all targets that make up your subset.
e.g. add_dependencies(subset foo1 foo2)

Then (assuming e.g. make) "make subset" will build that specific subset.
