The documentation of ADD_SUBDIRECTORY definitely needs work, but my
interpretation of "binary_dir" is it is the path of the build directory and
not the install directory (so it has nothing to do with your INSTALL command
directories). Thus your commands above are trying to map two separate
subdirectories to the same "foo" build subdirectory, and that is probably
causing the issue. Try keeping the two build subdirectories separate, i.e.,
foo1 and foo2 (or take the default build subdirectory names as in your first
working example).
