I'm trying to add a external library into my project in Qt Creator. Usually I am supposed to add the .dll, .lib or .a file (I am using Windows) when right-clicking my project > add library but in my case, there is no such file in the folder. Am I just blind and I keep overseeing it or do I have to create the file on my own or something like that? I would appreciate if there's a detailed solution for my problem.
