> Yikes; half a meg of code! It's plausible that the lib you checked is the output from the project's default build target (zstd), which "(...) includes dictionary builder, benchmark, and supports decompression of legacy zstd formats" https://github.com/facebook/zstd/tree/dev/programs https://github.com/facebook/zstd/tree/dev/programs The project also provides another build target, zstd-small, which is "CLI optimized for minimal size; no dictionary builder, no benchmark, and no support for legacy zstd formats" Also, take a look at what exactly is bundled with the binary. Odds are you're looking at a lib that statically links optional stuff that makes no sense shipping, let alone on an embedded target.
