[PLUGIN] OpenCV plugin for UE 4.19

Hello. Thank you for your awesome plugin!
But I can’t install it.

I renamed the folder to “OpenCV”, added “ThirdParty” directory in “OpenCV”, and added OpenCV directory into “MyProject/Plugins/”
Then launcheded MyProject, but it could not be rebuild. So, I tried to rebuild from souce code.
But rebuild fails with 108 errors, which are all of OpenCVSmileImpl.h and cpp.

Could you explain how I can fix this?

I’m using UE4.19
