The advantage is, a) bookkeeping e.g. cleanly namespacing stuff (which admittedly could be done with _/prefixes) and more importantly b) If you give an undefined name e.g. "boost_notalib" (or something mis-spelled) to target_link_libraries it'll just add "-lboost_notalib" to the link command - because it doesn't know if it's a custom library that it doesn't know about, or an undefined target. A name like "Boost::NotALib" can never be a library name, so if it's not a defined target you'll get an error at configuration time rather than build time. (Caveat: I am not an expert so could be completely wrong in incomplete or subtle ways, but this is definitely one way it makes a difference) Nick
