How to use sdl in Clion

Question

I’m fairly new in c++ , and don’t know how to use sdl in Clion. I’ve tried several ways, it’s like this currently:

Cmakelists:

project(cppsdl)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11 -lmingw32")
set(CMAKE_EXE_LINKER_FLAGS "-static-libgcc -static-libstdc++")

set(SDL_ROOT "C:/CppLibs/SDL2-2.0.4/i686-w64-mingw32")
include_directories(${SDL_ROOT}/include)
link_directories(${SDL_ROOT}/lib)

set(SOURCE_FILES main.cpp)
add_executable(cppsdl ${SOURCE_FILES})

target_link_libraries(cppsdl SDL2main SDL2)

main.cpp:

#include <iostream>
#include "SDL2/SDL.h"

int main(){
    if (SDL_Init(SDL_INIT_VIDEO) != 0){
        std::cout << "SDL_Init Error: " << SDL_GetError() << std::endl;
        return 1;
    }
    SDL_Quit();
    return 0;
}

Returns the following error:

The best way is to use Findsdl2.cmake download it and put it in the same project folder:

You can find it here: https://github.com/brendan-w/collector/blob/master/cmake/FindSDL2.cmake
