  The system library `libzstd` required by crate `zstd-sys` was not found.
  The file `libzstd.pc` needs to be installed and the PKG_CONFIG_PATH environment variable must contain its parent directory.
  PKG_CONFIG_PATH contains the following:
      - /nix/store/i4q9xzcvnk6gn3ga90j3n37616x11q9d-openssl-3.5.9-dev/lib/pkgconfig

  HINT: you may need to install a package such as libzstd, libzstd-dev or libzstd-devel.
