LNK2019 error when trying to use Stanford external C++ libraries in Visual Studio

Question

I am new to C++ and trying to learn from online Stanford CS106B course.

In this course, people from Stanford have provided external C++ libraries (Link to which is given below).

I have downloaded this zip file and extracted the contents. The folder structure looks like this

    └───tests

The include folder contains all the header file for the classes and functions and lib folder contains *.lib file used for static import of external library.

I tried importing external library in Visual Studio 2022 project by writing a dummy program shown below.

#include<iostream>
#include<string>
#include"simpio.h"

int main()
{
    int limit = getInteger("Enter exponent limit: ");
    std::cout << "Library import worked" << std::endl;
    return 0;
}

To include the external libraries, I followed the steps in the tutorial, who's link is given below.

The settings for included files in my projects are shown in the pictures below

and

Even after doing all of this, when I build my project, I am getting following errors

Severity    Code    Description Project File    Line    Suppression State

Error   LNK1120 1 unresolved externals  Project1    D:\to copy\C++\CS106B\trial_chapter\Project1\x64\Debug\Project1.exe 1   

I tried reading solutions from existing stack overflow questions but that did not help as I do not understand what am I doing wrong.

Can someone please help me with this..
