Thanks for pointing out that change, I built with boost1.71 (which is
available on Debian unstable and testing, but not default, see below)
for now, but that won't help for builds for older distros (aka stable),
unless I used internal boost there :/

I'd guess 1.67 given that it is from Rico and Ubuntu has:

>From https://packages.ubuntu.com/search?keywords=libboost-dev:

xenial (16.04LTS) (libdevel): Boost C++ Libraries development files
(default version)
1.58.0.1ubuntu1: amd64 arm64 armhf i386 powerpc ppc64el s390x
bionic (18.04LTS) (libdevel): Boost C++ Libraries development files
(default version)
1.65.1.0ubuntu1: amd64 arm64 armhf i386 ppc64el s390x
disco (19.04) (libdevel): Boost C++ Libraries development files (default
version)
1.67.0.1: amd64 arm64 armhf i386 ppc64el s390x
eoan (19.10) (libdevel): Boost C++ Libraries development files (default
version)
1.67.0.2: amd64 arm64 armhf i386 ppc64el s390x
focal (libdevel): Boost C++ Libraries development files (default
version)
1.71.0.0ubuntu1: amd64 arm64 armhf i386 ppc64el s390x

For Debian:

libboost-dev | 1.67.0.1      | stable       | amd64, arm64, armel,
armhf, i386, mips, mips64el, mipsel, ppc64el, s390x
libboost-dev | 1.67.0.2+b1   | testing      | amd64, arm64, armel,
armhf, i386, mips64el, mipsel, ppc64el, s390x
libboost-dev | 1.67.0.2+b1   | unstable     | amd64, arm64, armel,
armhf, i386, mips64el, mipsel, ppc64el, s390x
libboost-dev | 1.71.0.2      | experimental | amd64, arm64, armel,
armhf, i386, mips64el, mipsel, ppc64el, s390x

So yes, people are "stuck" with 1.67 on older distros and even Debian
unstable has only 1.67 (which is a problem, yes.)
