I would very much prefer if we didn't have the mandatory dependency on
the external LZ4 library.

This would be painful in case it's not available out of the box on the target
platform, and would add even more steps to the egregiously complicated
build process on Windows.  And building using an embedded copy of the
source isn't something new, as we already do that for utf8proc and with

Furthermore, we only require the core part of the LZ4 library — that is, two
relatively small files (lz4.c and lz4.h), which I think were specifically
designed this way to simplify the process of using LZ4 in various
