Your makefile is a mix of 2 slightly different syntaxes. That leads to the kind of confusion like when you write interpolation, is it bash interpolation or make interpolation, and so on. Make was made for system languages with slow compilation time where avoiding unneccesarily rebuilding and paralellization become crucial features. If you don't utilize or have a need for that then make does not bring anything to the table. If you DO have such need because your project is big now, you prolly also need monorepo workspace management etc, at which point you just use a modern tool like bazel.
