我试图添加相关的"-I"path_to_your_SDL_include_directory""，如在几个类似的帖子中所概述的，如this one。我尝试了三种方法;，将其添加到tasks.json、Makefile和c_cpp_properties.json。
我的文件结构如下。我的main.cpp在MyProject/src中。我已经将SDL的include文件夹的所有内容复制到MyProject/lib/SDL2_lib/include，并将lib文件夹复制到MyProject/lib/SDL2_lib/lib。SDL2.dll存在于MyProject/lib/SDL2_lib中。
下面是一个可视化的总结以及我的代码。
x1c 0d1x的数据
main.cpp个

#include <iostream>
#include <SDL.h>

const int WIDTH = 800, HEIGHT = 600;

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

    SDL_Window *window = SDL_CreateWindow( "Hello SDL WORLD", SDL_WINDOWPOS_UNDEFINED, SDL_WINDOWPOS_UNDEFINED, WIDTH, HEIGHT, SDL_WINDOW_ALLOW_HIGHDPI );

    if ( NULL == window )
    {
        std::cout << "Could not create window: " << SDL_GetError( ) << std::endl;
        return 1;
    }

    SDL_Event windowEvent;

    while ( true )
    {
        if ( SDL_PollEvent( &windowEvent ) )
        {
            if ( SDL_QUIT == windowEvent.type )
            { break; }
        }
    }

    SDL_DestroyWindow( window );
    SDL_Quit( );

    return EXIT_SUCCESS;
}

尽管如此，我还是得到了错误;

感谢您的帮助！
编辑：我还应该补充一点，添加一个随机文件名而不是SDL.h，会给整个include语句加下划线，而不仅仅是结尾。所以很明显，VSCode知道它的存在，只是没有将它添加到程序中，这是我的猜测
Edit 2：从powershell运行make给出以下错误;
