>I'm a hater of complexity and build systems in general.

But you already have a complex cmake build system in place. Adding a standard Docker image with all the deps for devs to compile on would do nothing but make contributing easier, and would not affect your CI/CD/testing pipeline at all. I followed the readme and spent half an hour trying to get this to build for MacOS before giving up.

If building your project for all supported environments requires anything more than a single one-line command, you're doing it wrong.
