HiPerConTracer uses it because zstd compression is fast and efficient. 
Since BOOST provides zstd support, it should be enabled. In its current 
state, a program source using BOOST and zstd successfully compiles (i.e. 
support seems to be there) but the linking fails. This seems to be a bug 
in the OpenBSD packaging, probably the same as in the FreeBSD package 
(which got fixed some time ago).

Currently, BOOST with zstd filter is working on Linux (Ubuntu/Debian, 
Fedora, OpenSUSE, Alpine), FreeBSD, NetBSD, and Solaris (OpenIndiana).
