Kind of.

Usually directories are added using ADD_SUBDIRECTORY(someDir).
In kdelibs/cmake/modules/MacroOptionalAddSubdirectory.cmake there is a macro 
called MACRO_OPTIONAL_ADD_DIRECTORY(someOtherDir). If this is used, you get a 
cmake option BUILD_someOtherDir, which cam be disabled using "make 
edit_cache"/ccmake/cmake -D ...).

I don't know how much this macro is used, I don't think it's used very much, 
so it can probably still be changed if required.

What exactly do you need it for ? Just building one or a few parts (then you 
could just go in these directories and build there) or build everything 
except some parts ?
