Adding SDL2 to Clion

Question

I am a beginner, I was trying to get SDL2 to work in clion but I failed. I've searched on youtube and google but nothing worked. I have SDL2.dll in the same folder as main.cpp My cmake file looks like this:

cmake_minimum_required(VERSION 3.8)
project(sdlTest)

set(CMAKE_CXX_STANDARD 17)

set(SOURCE_FILES main.cpp)

add_executable(sdlTest ${SOURCE_FILES})

add_library(SDL2.dll SHARED main.cpp)

set_target_properties(SDL2.dll PROPERTIES LINKER_LANGUAGE CXX)

I don't know what I'm doing wrong.

I tried running this example code from sdl:

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

int main(int argc, char* argv[]) {

SDL_Window *window;                    // Declare a pointer

SDL_Init(SDL_INIT_VIDEO);              // Initialize SDL2

// Create an application window with the following settings:
window = SDL_CreateWindow(
        "An SDL2 window",                  // window title
        SDL_WINDOWPOS_UNDEFINED,           // initial x position
        SDL_WINDOWPOS_UNDEFINED,           // initial y position
        640,                               // width, in pixels
        480,                               // height, in pixels
        SDL_WINDOW_OPENGL                  // flags - see below
);

// Check that the window was successfully created
if (window == NULL) {
    // In the case that the window could not be made...
    printf("Could not create window: %s\n", SDL_GetError());
    return 1;
}

// The window is open: could enter program loop here (see SDL_PollEvent())

SDL_Delay(3000);  // Pause execution for 3000 milliseconds, for example

// Close and destroy the window
SDL_DestroyWindow(window);

// Clean up
SDL_Quit();
return 0;
}

and I get this error:

I've tried both x64 and x86 and it's the same result but at the same time clion doesn't red-text the code, it thinks it's ok:

Any ideas what I'm doing wrong and how to fix? THANKS!

EDIT:

Cmake looks like this

cmake_minimum_required(VERSION 3.8)
project(sdlTest)

set(CMAKE_CXX_STANDARD 17)

set(CMAKE_MODULE_PATH ${PROJECT_SOURCE_DIR}/cmake)

find_package(SDL2 REQUIRED)

set(SOURCE_FILES main.cpp)

add_executable(sdlTest ${SOURCE_FILES})

set(SDL2_LIBRARY SDL2.dll)

target_link_libraries(sdlTest ${SDL2_LIBRARYS})

I get this error:

Found package configuration file:

C:/MinGW/lib/cmake/SDL2/sdl2-config.cmake

but it set SDL2_FOUND to FALSE so package "SDL2" is considered to be NOT
FOUND.

SECOND EDIT:

sdl2-config.cmake:

# sdl2 cmake project-config input for ./configure scripts
