At now, I have done this with a ADD_CUSTOM_TARGET(distclean)
which depends on clean and launches a perl script doing the
job (named with a .pl extension in order to be seen as
a script even on windows).

I did also post a feature request (2937) in order to be able to delete
a directory with a command line option of "cmake -E". It allows
being able to delete a directory in the same portable way,
as done with the script above but without a perl dependency.
It has just been implemented: the mail for a "closed" status has
been sent today :) . The command is "cmake -E remove_directory"
which removes the directory and all its content (files/subdirs).

And maybe the ability of deleting directories from
ADDITIONAL_MAKE_CLEAN_FILES have been
implemented (which would be consistent).
