Personally, I write my own build systems.

Any readily available build system is more of a meta-language onto which you code your own logic, but with limited control and capabilities. Might as well take control of the whole stack in a real programming language.

Building my own build system lets me optimize my workflow end-to-end, from modular version management, packaging and releasing, building and testing, tightly integrating whatever tool or reporting I want, all seamlessly under the same umbrella.

I mostly do C++, Assembly, eBPF, Python (including C++ Python modules), and multi-stage codegen on Linux, so I haven't really looked at the complexity of other languages or platforms.
