Remove usage of macdeployqt in favor of CMake BundleUtilities. BundleUtilities properly finds all dependencies and adds them to the .app automatically. It also fixes rpath and install_name issues for any of the binaries or dependencies

fn main() {
    #[cfg(target_os = "freebsd")]
    println!("cargo:rustc-link-search=native=/usr/local/lib");
}
