Hi,
currently mandriva has a packaging script which checks for uneeded linking in
package built files. For dwarves, it displays:
Warning: unused libraries in /usr/lib64/libdwarves_reorganize.so.1.0.0: libdw.so.1
libelf.so.1

The patch below fixes the issue (removing uneeded specified libraries and using
LINK_INTERFACE_LIBRARIES property, see
http://www.cmake.org/Wiki/CMake_FAQ#Why_are_libraries_linked_to_my_shared_library_included_when_something_links_to_it.3F)
