You can already do this today with:

1 - set(CPACK_...
2 - include(CPack)
3 - set(CPACK_...)
4 - include(CPack)

Simply including CPack a second time will configure the files according to
the new values set in step 3. No need for a bug tracker entry, no need to do
any update or re-config. Simply including CPack a second time will call
configure_file for the two files of interest: CPackConfig.cmake and
CPackSourceConfig.cmake...
