Totally, just use `zig cc` as an in-place replacement for clang and move forward from there as you feel comfrotable. I wrote a blog post about this approach: https://kristoff.it/blog/maintain-it-with-zig/
In particular, I explicitly don't want to rewrite 15000 lines of build system code, so anything that uses build.zig is a nonstarter.
zig build-obj file.zig
And then include the object file along with your other sources. How you do this will of course depend on your build system.
