Apologies to those who have downloaded this plugin and had it fail. This is my first time creating a plugin like this and I forgot to include all the needed dependencies to the install file. To those who may have already installed OpenCV dependencies alongside other plugins likely had no issues, but others who were trying to run this plugin without got a failed to load message.
I have remade the installer. You should just have to run it and it will take care of the extra dependencies, thank you for your patience and understanding!
