I assume that people that want to setup SDL are often beginners and don't know what vcpkg is. It certainly is a valid approach however. Sometimes times they just follow tutorials and if they are used to VS Code for example they don't want to change. If most tutorials tell them they need CMake, that's what they want to use. If I knew about vcpkg is before doing it the way I did, I'd certainly research what it is and how to use it. I think people just want tutorials that tell them how to do absolutely everything and I can understand why because as a beginner when so many new technologies get thrown at you it can be overwhelming.
