i have simple c++/sdl project in main.cpp:
#include <stdio.h>
#include <SDL2/SDL.h>
int main() {
printf("Initializing SDL.\n");
/* Initialize defaults, Video and Audio */
if((SDL_Init(SDL_INIT_VIDEO|SDL_INIT_AUDIO)==-1)) {
printf("Could not initialize SDL: %s.\n", SDL_GetError());
exit(-1);
}
printf("SDL initialized.\n");
printf("Quiting SDL.\n");
/* Shutdown all subsystems */
SDL_Quit();
printf("Quiting....\n");
exit(0);
}
and in the cmakelist.txt:
cmake_minimum_required(VERSION 3.0.0)
project(sdl2test VERSION 0.1.0)
include(CTest)
enable_testing()
add_executable(sdl2test main.cpp)
set(CPACK_PROJECT_NAME ${PROJECT_NAME})
set(CPACK_PROJECT_VERSION ${PROJECT_VERSION})
SET(SDL2_DIR C:/SDL2)
INCLUDE_DIRECTORIES(${SDL2_DIR}/include)
LINK_DIRECTORIES(${SDL2_DIR}/lib)
include(CPack)
but when go build it throws me:

i have a working mingw32 compiler form qtcreator, and one from code blocks, updated cmake as well as the extencions for vscode
