How to configure compiler when getting undefined reference to error in Vscode [duplicate]

I would like to know why I am having problems with non-existent files even though they are in the same directory.

This is my file organization:

I get the error:

I've already changed the folder files, and it still doesn't work, I'd like to understand what's happening and how I could solve it.

I'm using VScode, after researching more about the compiler, in tasks.json I changed it using an argument like "${workspaceFolder}/*.cpp" instead of "${file}", just as I discovered in an IDE tutorial , the code works if I put all the member functions in the .h files, but I still want to understand why, and how I can configure my compiler, apparently, even with the modifications I make to the settings it doesn't work. Could it have something to do with my compiler version?

Main.cpp:

#include "Vector3d.h"#include "Point3d.h"int main(){    Point3d p { 1.0, 2.0, 3.0 };    Vector3d v { 2.0, 2.0, -3.0 };    p.print();    p.moveByVector(v);    p.print();    return 0;}

Vector3d.h:

// Header file that defines the Vector3d class#ifndef VECTOR3D_H#define VECTOR3D_H#include "Point3d.h" // for declaring Point3d::moveByVector() as a friendclass Vector3d{    private:        double m_x{};        double m_y{};        double m_z{};    public:        Vector3d(double x, double y, double z);        void print() const;        friend void Point3d::moveByVector(const Vector3d& v);};#endif

Vector3d.cpp:

// Member functions of the Vector3d class defined here#include "Vector3d.h" // Vector3d class defined in this file#include <iostream>Vector3d::Vector3d(double x, double y, double z)  : m_x{x}, m_y{y}, m_z{z}{}void Vector3d::print() const{    std::cout << "Vector(" << m_x << " , " << m_y << " , " << m_z << ")\n";}

Point3d.h:

Point3d.cpp:
