it appears that the crates `core-graphics` and `core-graphics-types` are developed in the same repository [1]. Looking at the commit where the `core-graphics` version was set to 0.23.2 [2], the corresponding `core-graphics-types` crate version (0.1.3) already has the "link" feature, but version 0.1.1 (the version in Guix) does not. This seems to be a mistake in the `core-graphics` crate. As `kanata` depends on `core-graphics` version 0.23.2, you should add a package for rust-core-graphics-types with version 0.1.3 (the latest 0.1.* version) and use that instead in the #:cargo-inputs of rust-core-graphics-0.23.
