>" I think everyone has some story of banging their head against an asinine build process" Not my case. I have simple CMake files for my projects and have no problems building on Linux and Windows (I do not do Mac). I do use few libraries (Postgres, network - http/tcp/udp and some others). So far no troubles. I do remember it was way more complicated though. So I am not really missing "Rust eating C++'s lunch". I do understand there are some real life huge insanely complex projects with basillion options. Luckily I do not havbe to deal with that part.

CMake doesn't fetch your dependencies for you and ensure they're the version that your code is compatible with. I've cloned 5 year old C++ repos that use cmake and it's quite an effort to build them, mostly due to finding all the dependencies correctly versioed.

  I do not want it to fetch dependencies. I download those once and include it as a copy per project. Update on on-need basis. Over the years I have accumulated enough. To start new project all I have to do is - clone template directory and I am ready to go.

  > CMake doesn't fetch your dependencies for you and ensure they're the version that your code is compatible with. That’s a little too harsh. You can certainly make it do that via a combination of git tags (to build from source) and CMake modules/Find*, but yes, it’s much more cumbersome than cargo/npm/go

  This is true for almost all projects but things are getting better. I use CPM for a couple of years now and get the experience desired https://github.com/cpm-cmake/CPM.cmake https://github.com/cpm-cmake/CPM.cmake

Calling CMake a build „system“ is an overstatement given how unsystematic it is (you have to memorize everything)

  But building something more complex in Rust (than just grabbing a bunch of libraries from Cargo) becomes as tedious as what you typically expect in C++ land. I've read anecdotes of Rust devs struggling with build.rs (the official build scripting in Rust) similarly to how people bang their heads at CMake. This is why other C++ build systems like Bazel and Meson added Rust support, since Cargo/build.rs itself isn't sufficient enough for all use cases (especially when using it alongside with other systems languages.) And it's not too wild for something to think of adding Rust support for CMake as well...

    Don't forget Buck! Buck2 is implemented in Rust even.
