I compiled boost lib and got these.

To configure boost use the user config header
Then just look for the dynamic link lines and change to your desired configuration
// BOOST_ALL_DYN_LINK: Forces all libraries that have separate source,
// to be linked as DLL's rather than static libraries on Microsoft Windows
// (this macro is used to turn on __declspec(dllimport) modifiers, so that
// the compiler knows which symbols to look for in a DLL rather than in a
// static library). Note that there may be some libraries that can only
// be statically linked (Boost.Test for example) and others which may only
// be dynamically linked (Boost.Threads for example), in these cases this
// macro has no effect.
// #define BOOST_ALL_DYN_LINK
