OK, so it's not the same as editing the toplevel CMakeLists.txt, I see.

make help looks great, but make foo.o doesn't work:

$ make help
makeobj[0]: Entering directory `/mnt/devel/kde/build/trunk/KDE/kdelibs/kdewidgets'
The following are some of the valid targets for this Makefile:
... all (the default if no target is provided)
... clean
... depend
... install
... rebuild_cache
... kdewidgets
... makekdewidgets
... classpreviews.o
... makekdewidgets.o
... qrc_kdewidgets.o
makeobj[0]: Leaving directory `/mnt/devel/kde/build/trunk/KDE/kdelibs/kdewidgets'

$ make makekdewigets.o
makeobj[0]: Entering directory `/mnt/devel/kde/build/trunk/KDE/kdelibs/kdewidgets'
make: *** No rule to make target `makekdewigets.o'.  Stop.
makeobj[0]: Leaving directory `/mnt/devel/kde/build/trunk/KDE/kdelibs/kdewidgets'
