Why doesn't my sdl2 linking work even though i specified all libraries?

Question

I don't know why my code doesn't link.

Gcc Command:

g++.exe -g -std=c++17 main.cpp -ISDL2\include -o main.exe -LSDL2\lib -lmingw32 -lSDL2main -lSDL2

main.cpp:

#define SDL_MAIN_HANDLED
#include <SDL/SDL.h>

int main() {

    SDL_Delay(5000);

    return 0;
}

Error:

In function `main':
main.cpp:10: undefined reference to `SDL_Delay'
collect2.exe: error: ld returned 1 exit status

I tried many different orders of the parameters.

I also tried to reinstall / use other mingw / sdl2 releases.
