  Failed to find OpenSSL development headers.

  You can try fixing this setting the `OPENSSL_DIR` environment variable
  pointing to your OpenSSL installation or installing OpenSSL headers package
  specific to your distribution:

      # On Ubuntu
      sudo apt-get install pkg-config libssl-dev
      # On Arch Linux
      sudo pacman -S pkgconf openssl
      # On Fedora
      sudo dnf install pkgconf perl-FindBin perl-IPC-Cmd openssl-devel
      # On Alpine Linux
      apk add pkgconf openssl-dev

  See rust-openssl documentation for more information:

      https://docs.rs/openssl
