This is not needed.

You don't link against any library at all, or you didn't show enough of
your cmake file. To link against libboost_archive... its best to use

target_link_libraries( <yourapp> ${Boost_ARCHIVE_LIBRARY})

Then you don't need the LINK_DIRECTORIES call and cmake will actually
know the full path to boost libs so it can order the link dirs properly.
