Not being sarcastic but genuine because I do not know: are there any previous languages that have a build system like Zig?

I found really cool that you have a bunch of options to configure compilation of source code itself. Not just the compiler optimization but you can automate all kinds of things: https://ziglang.org/learn/build-system/#build-system

Languages, no. But for language-agnostic package managers, Nix/Guix and Gentoo are similar.

Sadly, Gentoo is not great for managing per-project dependencies in the same way as is done by npm, pipenv, etc. Nix however works great (if you can stomach its stdlib).
