Are the dynamic libraries being specified on the linker command line?
You absolutely should not be linking to both (ie both auto-linking and
specifying the lib's on the command line).
So either disable auto-linking with BOOST_ALL_NO_LIB (you will need to
enable dynamic linking as well with BOOST_ALL_DYN_LINK if you want to use
the DLL's), or remove the library dependencies in CMake and let the
auto-linking do it's work. If you take the former route, be *very* careful
that your build script picks the correct lib variant, otherwise you're
likely to see crashes and other strange hard to track down behavior.....
