VS Code is not linking my .cpp files with the main.cpp file when I try to compile it and changing the User settings.json in VS Code is not fixing it

Question

I am using Windows. I can't get VS Code to link the class .cpp file with the main.cpp file when I compile it.

This works:

#include "burrito.h"
#include <iostream>

using namespace std;

Burrito::Burrito(){
    b = 0;
    cout << "This is a default" << endl;
}

Burrito::Burrito(int b){
    this->b = b;
    cout << "This is parameterized " << endl;
}

int main(){
    Burrito bo;
    cout << bo.b << endl;

    Burrito* b;
    b = new Burrito(2);
    cout << b->b << endl;

    return 0;
}

This does not work:

#include "Burrito.h"
#include <iostream>

using namespace std;


int main(){
    Burrito bo;
    cout << bo.b << endl;

    Burrito* b;
    b = new Burrito(2);
    cout << b->b << endl;

    return 0;
}

I've found similar problems that say to go into the User settings.json and make this change:

"code-runner.executorMap": {
        "cpp": "cd $dir && g++ *.cpp -o $fileNameWithoutExt && $fileNameWithoutExt.exe"
    }

I'm still getting this error:

C:\Users\joe\OneDrive\Documents\collegepractice\programs\bp/main.cpp:12: undefined reference to `Burrito::Burrito(int)'

I also made this change and got the same issue.

I'm a sysadmin who is going back to school next semester trying to get practice with C++ so I apologize if this isn't enough good info. If you need more I am happy to provide it.

burrito.cpp:

#include "burrito.h"
#include <iostream>

using namespace std;

Burrito::Burrito(){
    b = 0;
    cout << "This is a default" << endl;
}

Burrito::Burrito(int b){
    this->b = b;
    cout << "This is parameterized " << endl;
}

burrito.h:

#ifndef BURRITO_H
#define BURRITO_H


class Burrito
{
    public:
        int b;
        Burrito();
        Burrito(int b);
};

#endif
