Building COSMIC apps on macOS is not possible because of this.

error: could not compile `smithay-client-toolkit` (lib) due to 2 previous errors

I think smithay-client-toolkit can't be a dependency for Cosmic apps on macOS. I think that needs to be fixed on whatever crate lists smithay-client-toolkit as a dependency to not do that on macOS.

[edfloreshz]

This is the dependency tree, reduced for legibility.

├── libcosmic v0.1.0 (https://github.com/pop-os/libcosmic.git#0ef3cced)
│   ├── cosmic-client-toolkit v0.1.0 (https://github.com/pop-os/cosmic-protocols?rev=c8d3a1c#c8d3a1c3)
│   │   ├── smithay-client-toolkit v0.19.2

[tronical]

Indeed, in that case if libcosmic were to enable cosmic apps on macOS, it is the crate that needs to be changed to not depend on wayland crates like these. For example in places like these.

[ids1024]

Yeah. Technically it would be possible to port smithay-client-toolkit to run on macOS (I've run wayland-rs on macOS), but you'd expect software not to pull in Wayland dependencies on macOS.
