Yes, non-rust dependencies can be a pain. We addressed this issue in three ways: 1. Sometimes, it just works™ if the crate has a copy of the C code and uses the cc crate to compile it. It's usually slow to compile C in a build script, but it works. 2. Sometimes, we write a custom BUILD script for direct dependencies and link external libraries by hand. Example: lmdb and lmdb-sys. 3. If all of the above is not an option or is too much work, we add a native library to the Docker container that runs our builds.

One thing that sticks out to me is that, while their code is open source, it has a restrictive license, the Apache License: https://github.com/dfinity/ic/blob/master/LICENSE - most open source projects opt for the MIT License.
