Why? If you build a static version of OpenCV it will be the same size as including opencv_world.dll with your application so there will be no difference apart from the number of files you include. i.e. One large application file or one smaller application file and one opencv_world.dll.
This was answered in your previous post
To clarify you can
Include in your project directory
Add to the the location to your system/user path
Build a static version of OpenCV and link against that but you need to clarify why you would want to do that and why option 1 and 2 are not suitable solutions for you?
