Subject: [PATCH] Add CI workflow to test compilation with each of the external
 compressors and with no external compressors. This is a sanity to make sure
 we don't introduce code dependencies on libraries that don't always exist
 (see https://github.com/facebook/zstd/pull/3497 for an example bugfix for
 such issue).
