3/// Exports an AUv2 entrypoint named `GetPluginFactoryAUV2` that wraps a global CLAP entrypoint (`clap_entry`) exported from the resulting shared library.
4/// Currently it only reexports the first plugin available through the CLAP entrypoint, but this limitation might be lifted in the future.

6/// Failure to export a CLAP entrypoint might result in linker errors or missing symbols.
