Nerdzmasterz You only want to use the extension? Well you can't because what's in that repo is just extension's source code. Extensions need to be built from their source code using a C++ compiler, like any other native app. A process known as "compiling/linking" or "building". If you don't have any experience in building C++ apps, your may find this process a bit involved. Once the extension is built, the resulting runtime files can be deployed (installed) into your project and used as a plugin.
Your best bet may be to contact the developer and ask them if they can provide a pre-built extension for your platform.
