CGAL with boost 1.39.0

In boost 1.39.0, the version of thread library is still 1.38.0, so the generated libraries was suffix by “1_38”. But in CGAL’s “FindBoost.cmake”, it will try to find the library with current version of boost, e.g, “1_39”, so it will not find the boost_thread component, error occured. You could manual modify the suffix from “1_39” to “1_38”, or use the older boost.
