## Issue Addressed NA ## Proposed Changes Adds support for using the [`cross`](https://github.com/rust-embedded/cross) project to produce cross-compiled binaries using Docker images. Provides quite clean and simple cross-compiles cause all the complexity is hidden in Dockerfiles. It does require you to be in the `docker` group though. ## Details - Adds shortcut commands to `Makefile` - Ensures `reqwest` and `discv5` use vendored openssl libs (i.e., static not shared). - Switches to a [commit](https://github.com/sigp/blst/commit/284f7059642851c760a09fb1708bcb59c7ca323c) of blst that has a renamed C function to avoid a collision with openssl (upstream issue: https://github.com/supranational/blst/issues/21). - Updates `ring` to the latest satisfiable version, since an earlier version was causing issues with `cross`. - Off-topic, but adds extra message about Windows support as suggested by Discord user. ## Additional Info - ~~Blocked on #1495~~ - There are no tests in CI for this yet for a few reasons: - I'm hesitant to add more long-running tasks. - Short-term bitrot should be avoided since we'll use it each release. - In the long term I think it would be good to automate binary creation on a release. - I observed the binaries increase in size from 50mb to 52mb after these changes.
