+SDL_JOYSTICK_HIDAPI is disabled by default. It can give you access to a lot
+more game controller devices, but it requires permission from the user before
+your app will be able to talk to the Bluetooth hardware. "Made For iOS"
+branded controllers do not need this as we don't have to speak to them
+directly with raw bluetooth, so many apps can live without this.
+
+You'll need to link with CoreBluetooth.framework and add something like this
+to your Info.plist:
+
+<key>NSBluetoothPeripheralUsageDescription</key>
+<string>MyApp would like to remain connected to nearby bluetooth Game Controllers and Game Pads even when you're not using the app.</string>
