Can't install OpenGL on MacOS10.14 - c++

Question

I've tried many ways to install OpenGL, using homebrew to install glfw and glew:
$ brew install glew glfw3
Or compile through source code:
$ cd glfw && cmake . && make && sudo make install
$ cd glew && make && sudo make install
Xcode is used to create the project. Opengl.framework, glut.framework, libglfw3. A and libglew. A are all added to the project. The header file path is / usr / local / include, and the library path is / usr / local / lib. Main.cpp source code:
#include <iostream>
#include <GL/glew.h>
#include <GLFW/glfw3.h>
void Render(void)
{
glClearColor(0.0f, 0.0f, 0.0f, 1.0f);
glClear(GL_COLOR_BUFFER_BIT);
glBegin(GL_TRIANGLES);
{
glColor3f(1.0,0.0,0.0);
glVertex2f(0, .5);
glColor3f(0.0,1.0,0.0);
glVertex2f(-.5,-.5);
glColor3f(0.0, 0.0, 1.0);
glVertex2f(.5, -.5);
}
glEnd();
}
int main(void) {
GLFWwindow* win;
if(!glfwInit()){
return -1;
}
win = glfwCreateWindow(640, 480, "OpenGL Base Project", NULL, NULL);
if(!win)
{
glfwTerminate();
exit(EXIT_FAILURE);
}
if(!glewInit())
{
return -1;
}
glfwMakeContextCurrent(win);
while(!glfwWindowShouldClose(win)){
Render();
glfwSwapBuffers(win);
glfwPollEvents();
}
glfwTerminate();
exit(EXIT_SUCCESS);
return 0;
}
Error in compilation:
Undefined symbols for architecture x86_64:
... (many can't find errors)
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
Can anyone help me?
