As you guessed this is impossible without backward compat' breakage.
e.g. be aware that with "CPACK_SET_DESTDIR" set to ON RPM and DEB
behavior changes
namely RPM package built with that may not be relocatable.

You may set(CPACK_SET_DESTDIR ON) only for ArchiveGenerator if you
use CPACK_CONFIG_PROJECT_FILE.

No problem.
