Can't get GLFW to link with g++

Ok, so I am trying to link GLFW to link but I'm having trouble.

Here is the error in console:

g++ -Iinclude -Llib -o out/main source/*.cpp
Undefined symbols for architecture x86_64:
  "_glfwInit", referenced from:
      _main in main-779346.o
ld: symbol(s) not found for architecture x86_64
clang: error: linker command failed with exit code 1 (use -v to see invocation)
make: *** [main] Error 1

Here is my makefile:

compiler = g++

main:
    $(compiler) -Iinclude -Llib -o out/main source/*.cpp
    ./out/main

Here is my file structure:

I'm on macos 10.15.7 and using Visual Studio Code as my editor. Hope someone can help!
