flag debug
  description:

  manual:
    True

flag sdl
  description:
    Enable SDL backend.
  default:
    True
  manual:
    True

flag sdl-renderer
  description:
    Enable SDL Renderer backend (requires the SDL_RenderGeometry function available in SDL 2.0.18+).
    The sdl configuration flag must also be enabled when using this flag.
  default:
    False
  manual:
    True

flag glfw
  description:
    Enable GLFW backend.
  default:
    False
  manual:
    True

flag examples
  description:
    Build executable examples.
  default:
    False
  manual:
    True

flag disable-obsolete
  description:
    Don't define obsolete functions/enums/behaviors. Consider enabling from time to time after updating to avoid using soon-to-be obsolete function/names.
  default:
    False
  manual:
    True

flag use-wchar32
  description:
    Use 32-bit for ImWchar (default is 16-bit) to support unicode planes 1-16. (e.g. point beyond 0xFFFF like emoticons, dingbats, symbols, shapes, ancient languages, etc...)
  default:
    True
  manual:
    True

flag use-ImDrawIdx32
  description:
    Use 32-bit vertex indices (default is 16-bit) is one way to allow large meshes with more than 64K vertices.
    Your renderer backend will need to support it (most example renderer backends support both 16/32-bit indices).
    Another way to allow large meshes while keeping 16-bit indices is to handle ImDrawCmd::VtxOffset in your renderer.
    Read about ImGuiBackendFlags_RendererHasVtxOffset for details.
  default:
    True
  manual:
    True
