A variable setting the app ID string.
Defined in <SDL3/SDL_hints.h>
#define SDL_HINT_APP_ID "SDL_APP_ID"
This string is used by desktop compositors to identify and group windows together, as well as match applications with associated desktop settings and icons.
This will override SDL_PROP_APP_METADATA_IDENTIFIER_STRING, if set by the application.
This hint should be set before SDL is initialized.
This hint is available since SDL 3.0.0.
