People with different skillsets can repay in different ways, and that's not a bad thing. Not that anybody really has to repay anything. But in any case, I would certainly appreciate a second pair of eyes from somebody with expert knowledge on Meson once I have something to show. I had a deeper look at the CMake build infra that we have and figured that it does make a whole lot of assumptions that autoconf wouldn't make. Those assumptions can of course be removed, and I'd be okay with doing that eventually. But for now I'm hacking up an initial iteration of Meson that is good enough to build, install and hopefully test Git. The intent here isn't quite to preclude us from using CMake as "official" build system, but rather to make it possible to compare the different build systems with actual code, where our choices will be plain Make, autoconf, Meson and CMake. That should hopefully lead to a more informed discussion. > Although I'm uninterested in personally working on cmake, as you > probably predicted. Fair. Patrick
