So, it's trying to link to a static library.

Those are dynamic link libraries and import libraries corresponding to them.

Right, because you are linking to import library, not a static library.

I think you should define BOOST_ALL_DYN_LINK when building you application, to
inform autolink to use dynamic libraries.
