in KDE we have the macro
macro_optional_add_subdirectory()
http://websvn.kde.org/trunk/KDE/kdelibs/cmake/modules/MacroOptionalAddSubdirectory.cmake?revision=940658&view=markup

E.g. if you do 
macro_optional_add_subdirectory(project1)

the subdir project1/ will be added like with normal add_subdirectory(), but 
additionally you'll have a cmake option "BUILD_project1", which you can 
enable and disable, and when disabled, the directory will not be added.

E.g. with the approach above, you can use cmake-gui or ccmake to have a look 
at the available options.

Does that help ?
