openssl not installed

Describe the bug

Steps to reproduce the behavior:
  run pkg_config fail: "`\"pkg-config\" \"--libs\" \"--cflags\" \"openssl\"` did not exit successfully: exit status: 1\nerror: could not find system library 'openssl' required by the 'openssl-sys' crate\n\n--- stderr\nPackage openssl was not found in the pkg-config search path.\nPerhaps you should add the directory containing `openssl.pc'\nto the PKG_CONFIG_PATH environment variable\nNo package 'openssl' found\n"

  --- stderr
  thread 'main' panicked at '

  Could not find directory of OpenSSL installation, and this `-sys` crate cannot
  proceed without this knowledge. If OpenSSL is installed and this crate had
  trouble finding it,  you can set the `OPENSSL_DIR` environment variable for the
  compilation process.

  Make sure you also have the development packages of openssl installed.
  For example, `libssl-dev` on Ubuntu or `openssl-devel` on Fedora.

  If you're in a situation where you think the directory *should* be found
  automatically, please open a bug at https://github.com/sfackler/rust-openssl
  and include information about your system as well as this message.

  $HOST = x86_64-unknown-linux-gnu
  $TARGET = x86_64-unknown-linux-gnu
  openssl-sys = 0.9.76

  ', /home/navy/.cargo/registry/src/github.com-1ecc6299db9ec823/openssl-sys-0.9.76/build/find_normal.rs:191:5
  note: run with `RUST_BACKTRACE=1` environment variable to display a backtrace```

**Expected behavior**
Install openssl automatically

Thanks for reporting this! I opened #216 to switch to rusttls instead of openSSL, which should fix this issue. Until then, you can try running apt install libssl-dev. Alternatively, you can use our pre-built binaries at https://github.com/dora-rs/dora/releases/tag/v0.2.0.

OK, thanks!
