        Orbital depends on an unreleased third-party library and cannot be built without the required `core.cmake` script.
        Functionality related to PS4 emulation/introspection is open-sourced *only* as documentation for fellow developers and hackers.
        To build Orbital, wait for the upcoming release of `core.cmake` or reimplement one yourself that includes/links QEMU instead.
        Please do NOT ask for help/support related to `core.cmake` issues.")
