Merged requested to merge rleigh/cmake:boost-1.67 into master
Add support for Boost 1.67 (tested against the beta). This release adds two-digit Python version suffixes; add support for these, as well as for the non-standard distribution-specific variants in existence before this Boost release.
I've also bumped a few versions in the documentation examples so it's a bit more up-to-date.
