SDL2 project using c++ on windows won't compile

Question

Whenever I try and compile with mingw32-make -f .\MakeFile it outputs this error:

g++ -Iinclude -Iinclude/sdl -Iinclude/headers -Llib -o test src/*.cpp -lmingw32 -lSDL2main -lSDL2 -lSDL2_image

C:\Users\spr\AppData\Local\Temp\ccpQRKDb.o:main.cpp:(.text+0xf): undefined reference to `SDL_Init'
C:\Users\spr\AppData\Local\Temp\ccpQRKDb.o:main.cpp:(.text+0x33): undefined reference to `SDL_GetError'

collect2.exe: error: ld returned 1 exit status
mingw32-make: *** [.\MakeFile:2: all] Error 1

Here is the code:

#include <SDL.h>
#include <SDL_image.h>
#include <iostream>

int main(int argc, char* argv[])
{
    if(SDL_Init(SDL_INIT_VIDEO) > 0)
    {
        std::cout << "SDL_INIT FAILED. SDL_ERROR: " << SDL_GetError() << std::endl;
        return 1;
    }

    return 0;
}

I followed this tutorial on how to set up SLD2 with VScode on Windows: https://www.youtube.com/watch?v=9Ca-RVPwnBE
