This appears to have been misconceived, at least in the case of MSVC
builds, as I have just discovered. It is entirely possible to have the
lz4 libraries installed and build with them but not have the .exe, and
unlike the configure case the MSVC build system doesn't conduct any test
for it, resulting in a nasty looking TAP test failure. I assume similar
failures are possible with zstd and maybe gzip.
