This is the error I'm getting:
Compiling opencv v0.91.3

I dont understand the meaning of that. I installed opencv on my system using homebrew but I guess I needed to do a specific installation for Rust so I went to crates.io and pasted the opencv version in my Cargo.toml
Then tried to run cargo build, all the other packages built successfully except this one.
This is the Cargo.toml file:
[package]
name = "rust-opencv"
version = "0.1.0"
edition = "2021"
[dependencies]
opencv = "0.91.3"
cgmath = "0.18.0"
algebra = "0.2.0"
You need to enable the clang-runtime feature to properly build the libclang on MacOs
[dependencies]
opencv = { version = "0.91.3", features = ["clang-runtime"] }
