I was trying to setup a project with GLFW and GLAD. The file structure is as following:
opengl
│ build.bat
│ main.c
│
├───bin
│
├───deps
│ └───lib-vc2022
│ glfw3.lib
│
└───include
├───glad
│ glad.c
│ glad.h
│
├───GLFW
│ glfw3.h
│ glfw3native.h
│
└───KHR
khrplatform.h
I have run vcvarsall.bat and set the compiler to be x64 so I have access to the msvc compiler.
To compile the code I ran build.bat which contains: (I got the 64 bit Prebuilt Windows binary from the glfw website)
@echo off
if not exist bin mkdir bin
pushd bin
cl /Zi /Od /I..\include C:\Dev\opengl\include\glad\glad.c ..\main.c /link /NODEFAULTLIB /LIBPATH:..\deps\lib-vc2022 glfw3.lib kernel32.lib user32.lib gdi32.lib winspool.lib comdlg32.lib advapi32.lib shell32.lib ole32.lib oleaut32.lib uuid.lib odbc32.lib odbccp32.lib opengl32.lib
popd
main.c contains the code required to open a window in glfw.
The files I have included in main.c is as following:
#include <glad/glad.h>
#include <GLFW/glfw3.h>
#include <stdio.h>
I then ran build.bat and got the following errors:

I managed to solve this, by adding this to my batch file:
@echo off
if not exist bin mkdir bin
pushd bin
set LIBRARIES=glfw3.lib user32.lib gdi32.lib shell32.lib
