//! Build-time link configuration for the `liboakengine` cdylib.
//!
//! The dylib now carries the module C ABIs itself (oakundo_*, oakcommon_*,
//! ... — see Cargo.toml), so the only remaining undefined imports are the
//! C++ host-provided symbols the modules call directly: `oakcore_*`
//! (liboakcore's `oakcore_audioparams_*` / `oakcore_rational_*`, called by
//! oakcodec) and `fb_find_best_pix_fmt_of_list` (ffmpeg_bridge, called by
//! oakcommon's pixel-format helper). Those live in the host Oak process,
//! which loads this dylib, so macOS `ld` must accept them as runtime
//! lookups instead of link-time errors. Only the cdylib gets this flag —
//! the rlib/staticlib (and the worker/cli consumers) are unaffected.
