windows下的VSCode学习OpenGL无法显示运行结果

执行test.exe时，没有弹窗出现

launch.json中的"externalConsole"改为true和false都不行

下面是我用到的代码，请问怎么才能出现结果呢？

#include<iostream>
#include<GL/gl.h>
#include "glfw3.h"

int main(){
    GLFWwindow* window;

    if(!glfwInit())return -1;

    window = glfwCreateWindow(470, 320, "TestOpenGL", NULL, NULL);
    if(!window){
        glfwTerminate();
        return -1;
    }

    glfwMakeContextCurrent(window);
    while(!glfwWindowShouldClose(window)){
        glBegin(GL_TRIANGLES);

        glColor3f(1.0, 0.0, 0.0);
        glVertex3f(0.0, 1.0, 0.0);

        glColor3f(0.0, 1.0, 0.0);
        glVertex3f(-1.0, -1.0, 0.0);

        glColor3f(1.0, 0.0, 1.0);
        glVertex3f(1.0, -1.0, 0.0);

        glEnd();
        glfwSwapBuffers(window);
        glfwPollEvents();
    }
    glfwTerminate();
    return 0;
}
