Hi,

It's probably a bug.
I've noticed this a while ago on Redhat Linux (worked fine on Ubuntu
though) but haven't got arround to investigate why that happens - for
me it's lower priority as not all package generators even support
absolute paths.

As a workarround you could use relative paths and choose for INSTALL
and PACKAGING prefix / and manage other relocation subpaths with
relative paths from
http://www.cmake.org/cmake/help/v3.2/module/GNUInstallDirs.html (with
CPack 3.2 and above you can use multiple relocation prefixes).
