Technically no, but quite often they are easier to install and tinker with than C/C++ projects (for instance usually you just need to clone the repo and run either 'cargo build' or 'zig build', and it mostly 'just works' no matter the platform).

Some C/C++ projects which have switched to cmake are equally easy to build (well not quite: "mkdir build && cd build && cmake .. && cmake --build ."), but it's definitely not the norm.
