  = note: some `extern` functions couldn't be found; some native libraries may need to be installed or have their path specified
  = note: use the `-l` flag to specify native libraries to link
  = note: use the `cargo:rustc-link-lib` directive to specify the native libraries to link with Cargo (see https://doc.rust-lang.org/cargo/reference/build-scripts.html#rustc-link-lib)

Steps to reproduce

Running in a container.

    pub async fn new(opt: &ContentIndexSettings) -> Self {
        let db_path = db_check_path(&opt.context_index_name, "usearch")
            .await
            .unwrap();
        let usearch_filename = format!("{}/index.usearch", db_path);
        let options = IndexOptions {
            dimensions: 1024,
            metric: MetricKind::Cos,
            quantization: ScalarKind::F32,
            connectivity: 0,
            expansion_add: 0,
            expansion_search: 0,
            multi: false,
        };
        let index = new_index(&options);
        let index = match index {
            Ok(index) => index,
            Err(e) => panic!("Failed to create index: {}", e),
        };
        index.load(&usearch_filename).unwrap();
        Self {
            index,
            usearch_filename,
        }
    }
