I agree, then the question is should every deb package built by CPack being
owned by root?

Currently people making deb with CPack without having fakeroot installed
get their
package with current user owning. i.e. fakeroot is not ALWAYS used.

Now if you find a way to set root ownership in archive created by CPackDeb
then every deb package
will have those right.

My opinion (from the various bug report related to deb ownership) is that
is OK since creating a deb including
whatever non-root user in it is a mistake.

So the "proper" way to go may  be to use libarchive directly in CPackDeb to
create tar in order to better control ownership of the created bits.

This is definitely more work, but this looks the proper way to me.
