Build Fail

[Knovnov]

Hi, thanks for creating this project. This is spelled "program", by the way.
This repository contains a small programm to decode a backup produced by Signal Android.

Quite frankly, I have no idea what I'm doing or have any experience in rust, and I've just had some (probably rookie) errors that I don't quite understand how to solve. When, I try to build, this happens.

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-pc-windows-msvc
$TARGET = x86_64-pc-windows-msvc
openssl-sys = 0.9.63

It looks like you're compiling for MSVC but we couldn't detect an OpenSSL
installation. If there isn't one installed then you can try the rust-openssl
README for more information about how to download precompiled binaries of
OpenSSL:

This is on windows 10. Sorry to bother you, I'd be very thankful for assistance.
