#define SDL_ELF_NOTE_DLOPEN(feature, description, priority, ...) \
    SDL_ELF_NOTE_INTERNAL(                                       \
        "[{\"feature\":\"" feature                               \

You can do this by adding the following to the global scope:

SDL_ELF_NOTE_DLOPEN(
    "png",
    "Support for loading PNG images using libpng (required for APNG)",
    SDL_ELF_NOTE_DLOPEN_PRIORITY_RECOMMENDED,
    "libpng12.so.0"
);

Or if you support multiple versions of a library, you can list them:

// Our app supports SDL1, SDL2, and SDL3 by dynamically loading them
SDL_ELF_NOTE_DLOPEN(
    "SDL",
    "Create windows through SDL video backend",
    SDL_ELF_NOTE_DLOPEN_PRIORITY_REQUIRED
    "libSDL-1.2.so.0", "libSDL2-2.0.so.0", "libSDL3.so.0"
);

This macro is available since SDL 3.4.0.
