The classic build system used by C programmers which is now commonly used by unix sysadmins in Git repos because it's such a short command.
It's hard to find a shorter easier build command than running:
maketo run whatever build commands you want.
Even when I use Maven, Gradle, SBT, Pip, Cpanm, Go Build etc... I wrap them in a Makefile because it makes the
commands shorter and captures any special command line arguments that you may want to pass to the build systems.
All of my repos use Makefiles to standardize CI/CD across different systems.
