Compared to the autotools I'd say make is fairly decent! But yeah, it's a mess. I wonder if it's really possible to improve significantly over the status quo if you're not willing to compromise on flexibility and design the build system alongside the language itself, like Rust does with cargo for instance.

Make on the other hand is completely language agnostic, you can use it to compile C, Java, LaTeX, or make your taxes. Make is a bit like shell scripts, it's great when you have a small project and you just want to build a few C files for instance[1] but when it starts growing there always comes a point where it becomes hell.

[1] And even then if you want to do it right you need compiler support to figure header dependencies out, like GCC's various -M flags.
