Pretty much all newer languages massively simplify their build processes by establishing a bunch of common-sense conventions: the output directory is always the same, all *.foo files in a directory are automatically considered source files, the output is identical to the directory name, things like that. They also include proper versioning of dependencies instead of "just assume /usr/include/foo/foo.h is the version we want, yolo". In principle it's very much possible to do all of this in C or C++, which would massively simplify stuff. But both C and C++ being a "design by committee" affair there will be endless fighting over which conventions to choose so I'm not holding my breath.
