CMake does that and is a truly demented implementation, mixing user-specified initial state (supplied the first time you run CMake and carried on to future argument-less invocations), derived state, and cached compiler locations and versions in a single CMakeCache.txt file. Edit CMakeLists.txt? Time to delete CMakeCache.txt! Upgrade your compiler? Time to delete CMakeCache.txt! I haven't used Meson all that much, but I recall it's a bit better than CMake but I still ran into a similar issue at one point.
