Eric already covered this part - use relative paths instead ( no / at the

Pre/postinstall scripts are outside what CPackRPM is handling automatically
but you can still use the relocation paths as supported by RPM.
Example for single relocation path:
set(CPACK_PACKAGING_INSTALL_PREFIX "/usr") # this will become the
relocation path - becomes first relocation path
Example for multiple relocation paths:
set(CPACK_RPM_RELOCATION_PATHS "etc/foo" "opt/bar") # two paths that will
be relocatable - etc will become first relocation path and opt the second
one
set(CPACK_RPM_NO_INSTALL_PREFIX_RELOCATION ON) # this will remove the
default /usr from relocation paths
set(CPACK_PACKAGING_INSTALL_PREFIX "/a") # relative paths will be prefixed
with /a - there is a bug that prevents you from using "/" only for
relocation paths so you might decide to patch CPackRPM.cmake yourself [1]

Now for the postinstall script each relocation path becomes a variable in
RPM (RPM_INSTALL_PREFIX0 for first relocation path, RPM_INSTALL_PREFIX1 for
the second and so on) so what you have to do in your script is instead of
writing something like this:
chown someone:somegroup /etc/some_non_relocatable_path/some_file
you should write:
chown someone:somegroup
${RPM_INSTALL_PREFIX0}/some_non_relocatable_path/some_file
