That's due to commit e9537321a74a2b062c8f7a452314b4570913f780.
Possible responses look like:
- Use 0 which also means "default" (need to verify that works across versions);
- Or #ifndef ZSTD_CLEVEL_DEFAULT #define ZSTD_CLEVEL_DEFAULT 3;
- Add a test for a minimum zstd version v1.3.7. This may be a good idea for
v15 in any case, since we're using a few different APIs (at least
ZSTD_compress and ZSTD_compressStream2 and execve(zstd)).
