cmake .. -G Xcode suddenly fails with the project it used to work with

Question

I have a project, where I used to do cmake .. -G Xcode to build for Xcode and it used to work fine. I haven't touched the project for a month or so and when I ran the same command today I got an error below.

The only thing I changed since the last time I built the project was doing some Rust tutorial, so I installed some things for Rust, but I don't remember what exactly.

What could have happened?

将 cmake 更新到最新版本（3.18.4）为我解决了这个问题。
