I'll look into doing that. I think populating
INTERFACE_COMPILE_DEFINTIONS with BOOST_${LIBRARY_NAME}_NO_LIB seems the
obvious choice. In addition I can provide a Boost::disable_autolinking
target to disable it for the complete library.

Another option is to wrap FindBoost and simply unset ${Boost_LIBRARIES}
on Windows after it completed and to make sure the link directories are
set.
