-libimagequant v2 used to be a C library. libimagequant v4 is written entirely in Rust, but still exports the same C interface for C programs. You will need to install Rust 1.60+ to build it, and adjust your build commands. If you do not want to upgrade, you can keep using [the C version of the library](https://github.com/imageoptim/libimagequant/tree/2.x) in the `2.x` branch of the [repo](https://github.com/ImageOptim/libimagequant).
