[boost] 1.67 libraries missing autolink/dependency information

When updating the CMake FindBoost dependencies for 1.67, it was noted that the stacktrace library wasn't being included. Closer examination showed that it doesn't have any autolink information in the headers: grep -R BOOST_LIB_NAME . | grep stacktrace grep -R BOOST_LIB_NAME . | grep contract (for example). Does this library work on Windows? Is it expected that the autolink information is missing, or is this something which needs adding? The same applies to the "contract" library. Do either of these libraries have any other dependencies on other Boost libraries? Thanks, Roger
