Maybe I don't understand the problem but writing something like this:
install(TARGET some_target DESTINATION
"${INSTALL_PREFIX}/some_location") where install_prefix could be set
as "${CURRENT_PROJECT}/${CURRENT_PLATFORM}" (should be a relative
path)

and then write:
set(CPACK_PACKAGING_INSTALL_PREFIX "${RELOCATABLE}") where relocatable
can be "/"

should produce what you want.

If you really don't want to write "${INSTALL_PREFIX}" for each install
location then your solution would probably be the best way to go but
IMO setting install location is the cleaner solution.
