Looks like you finally got to where I was to. Another thing, and I'll
confirm this when I get a chance, but I think from my messing around
that with cmake 2.8 you can not only set the install directory for
relative install locations, but also force absolutely referenced
install locations (e.g. INSTALL(FILES ${DOCS} /opt/ros/ycp/docs)) with
the destdir command. Currently, my cpack configuration is like
follows:

SET(CPACK_SET_DESTDIR ON)
SET(CPACK_INSTALL_PREFIX "${CMAKE_INSTALL_PREFIX}")
# Other cpack calls
INCLUDE(CPack)
