SDL简单循环窗口(使用xmake)

//main.cpp

#include 
#pragma mark - thirdpartylib

#pragma mark - windowconst

const int WIDTH = 400;
int main(int argc, char const *argv[])
{
    // 一定是     !=0
    if ((SDL_Init(SDL_INIT_EVERYTHING)) != 0)
    {
        return 1;
    }

    int x = 0;
    SDL_Window *window = SDL_CreateWindow("shae", SDL_WINDOWPOS_CENTERED, SDL_WINDOWPOS_CENTERED,
                                          WIDTH, WIDTH, SDL_WINDOW_SHOWN);

    SDL_Renderer *render = SDL_CreateRenderer(window, -1, 0);

    bool is_quit = false;
    SDL_Event event;

    SDL_Rect screenRect;
    SDL_GetDisplayBounds(0, &screenRect);
    SDL_SetWindowBordered(window, SDL_FALSE);
    SDL_SetWindowMouseRect(window, &screenRect);

            {
                is_quit = true;
            }
        }
        x += direction * 10;
        if (x + WIDTH >= screenRect.w)
