This will roughly do what I want, but I think it does not correctly express things. For the sub-project, yadda is not optional, and if I call cmake in that sub-project's directory, it should fail. What I think would be appropriate would be a command add_subdirectory_optional(...) or add_subdirectory_and_ignore_errors(...) or something similar.
