You should dig the mailing list archive.
cmake erase is not that easy to implement because using
cmake you may use

ADD_CUSTOM_COMMAND
EXECUTE_PROCESS and the like
which may run tools which actually generates outputs (files, directory etc...)
and cmake is not even aware of, only the user who write the corresponding
cmake script knows it.

And yes ADD_CUSTOM_COMMAND as an OUTPUT argument but
may be the user does not list all generated file there, may be because
he cannot guess how many file will be generated.

Having a separate source and build tree is really the best way to go,
then removing the build tree is easy :=)
