UE 4.8 joystick support

What version of the engine did you get that working on ? If push comes to shove I would use 4.7.6, but i tried to add this plugin to a 4.7.6 project and it says:

The following modules are missing or built with a different engine version:

UE4Editor-JoystickPlugin.dll

Would you like to rebuild them now?

when i click yes it says:

projectName could not be compiled. Try rebuilding them from source manually
