native/optex_copt/build.rs 

//! Locate and link the installed COPT (Cardinal Optimizer) library. Unlike

//! Gurobi's, the import library name is unversioned (copt.lib / libcopt.so),

//! so COPT_HOME/lib is used directly. This crate is only compiled when the

//! Elixir side detects COPT_HOME.



use std::{env, path::PathBuf};



fn main() {

    println!("cargo:rerun-if-env-changed=COPT_HOME");



    let home = env::var("COPT_HOME")

        .expect("COPT_HOME must be set to the COPT install dir to build optex_copt");

    let lib_dir = PathBuf::from(&home).join("lib");



    println!("cargo:rustc-link-search=native={}", lib_dir.display());
