I just came across a similar problem, but with glfw. If you manually included the library, you probably want to make a new project because I have no idea how to revert all those settings back to normal. What you want to do is follow all these instructions: https://learn.microsoft.com/en-us/vcpkg/get_started/get-started-msbuild?pivots=shell-powershell, and make sure manifest mode is enabled in your project settings. then run your program once and visual studio will download the library. make sure you include dependencies.
