I've re-written the documenation:

-------------------------------------------------------------------------
ADD_DEPENDENCIES
    Add a dependency between top-level targets.

      ADD_DEPENDENCIES(target-name depend-target1
                       depend-target2 ...)

    Make a top-level target depend on other top-level targets.  A
    top-level target is one created by ADD_EXECUTABLE, ADD_LIBRARY, or
    ADD_CUSTOM_TARGET.  Adding dependencies with this command can be used
    to make sure one target is built before another target.  See the
    DEPENDS option of ADD_CUSTOM_TARGET and ADD_CUSTOM_COMMAND for adding
    file-level dependencies in custom rules.  See the OBJECT_DEPENDS
    option in SET_SOURCE_FILES_PROPERTIES to add file-level dependencies
    to object files.
