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:
make
to 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.
All of my repos use Makefiles to standardize CI/CD across different systems.
