You could do it in two separate steps and without absolute path:
execute_process(COMMAND ${CMAKE_COMMAND} -E create_symlink
../../some_relative_path/bin/realfile linkfile) # at this point path
doesn't need to point to the location of existing file
install(FILES ${CMAKE_CURRENT_BINARY_DIR}/linkfile DESTINATION
some_relative_path COMPONENT libraries)
Not certain which CPack package generator you're using but in case of
CPackRPM there is quite some automated handling of symlink paths (even
support for symlinks in relocatable rpm packages).
In this file are some examples of using symlinks in combination with
CPackRPM (never checked how they behave with other CPack package generators
though...):

Side note - during packaging CPACK_PACKAGING_INSTALL_PREFIX is used instead
of CMAKE_INSTALL_PREFIX.
