  = note: ld: library not found for -lzstd
          clang: error: linker command failed with exit code 1 (use -v to see invocation)

Fixed by following:

1. $ brew install zstd xxhash
2. Add rustflags below in ~/.cargo/config:

[target.x86_64-apple-darwin]
rustflags = [
  "-C", "link-arg=-undefined",
  "-C", "link-arg=dynamic_lookup",
]
