"cargo install cargo-semver-checks" fails to build since version 0.24.0 due to compile issue with cmake

[whimboo]

Steps to reproduce the bug with the above code

Run the following command: cargo install cargo-semver-checks --version 0.24.0.

Trying to install older versions work fine.

Actual Behaviour

error: failed to run custom build command for `libz-ng-sys v1.1.15`

Thanks for the report, and sorry for the frustrating situation.

It appears that one of our dependencies has started requiring that cmake be available, per the error message: is cmake not installed?

Unfortunately, it doesn't seem to me like we have any great options here:

• We don't directly depend on that library — it's a transitive dependency somewhere deep in the tree — so we can't easily drop it.
• There's no way to specify to cargo that cmake is required. If cmake isn't available, cargo install will simply never work — it cannot install cmake automatically nor proactively error out with a good error message if it isn't available.
• We could document that cmake is needed in our README, but since this is a transitive dependency, that requirement might drift over time. And the README is probably not something people will check before running cargo install anyway.
• We already provide a prebuilt binary for aarch64-apple-darwin which users are encouraged to use. But obviously some users will prefer to compile the tool themselves, so there's still a problem.

What do you think we should do?

So I had a look at the repository for libz-sys if there is a known issue for that and I found rust-lang/libz-sys#93. It's not directly related but installing cmake via brew install cmake as mentioned over there fixes the error for me.

Most people might have cmake already installed so feel free to close, or maybe have an entry in the FAQ that mentions that?
