I realise that this question has been asked a million times, but I have gone through those solutions and they have not helped me solve the issue.
I am trying to import a library called PDNALib.lib and a few header files. So I created a folder in the project director called "Include" and added the requisite files. I have attached the images below.

The compiler still isn't able to find the library. Is there something I am doing wrong? Should I follow some other step?
