You could place your code into a dynamically linked library (DLL). You would still need to refer to it with a little bit of c#.

That won't work at all - The DLLs in that link are expected to contain .Net code. Code written in C++ in OpenCV would be native code, it cannot be imported as a DLL in Unity like that.

You can still link to it as a DLL, but it must be called as a plugin in Unity, and you must call its functions with the extern keyword in C#. The link you need is this one:

Notice that plugins are a Pro feature.
