## Build
There are some licensing issues at present, so you shouldn't build this plugin.
To get a `target/debug/libpurple_delta.so`, just run `cargo build`.
`deltachat-core-rust` uses a vendored openssl 1, unconditionally links it, and
is MPL-licensed.
`purple-plugin-delta` is GPLv3 without the [OpenSSL exemption](https://people.gnome.org/~markmc/openssl-and-the-gpl.html)
`libpurple` itself is GPLv2 without the OpenSSL exemption.
There's no point to `purple-plugin-delta` adding the OpenSSL exemption because
`libpurple` lacks it, and in any event, it will be unnecessary with the next
major version of OpenSSL. So, time should resolve this for us one way or another.
Since purple-plugin-delta is made to link against libpurple, which is GPLv2
without the "OpenSSL exemption", distributing something that linked against
OpenSSL 1 would be a licensing violation. Instead, we configure the build system
so we statically link against a vendored OpenSSL 3 instead. This has only been
possible since 2021-09-07.
Significant code using the WTFPL includes the [libpurple-rust bindings](https://github.com/sbwtw/libpurple-rust)
