Cmake 找不到 msys2 (windows) 的 luajit 包

如何解决Cmake 找不到 msys2 (windows) 的 luajit 包

我在将库包含到我的 cmake 项目中遇到了另一个问题。 项目规格是：

IDE：Visual Studio 代码

套件：GCC 10.3.0 Mingw64（通过 msys2）

Freetype 和 Luajit 两个包也是通过 msys（在 mingw64 模式下）安装的。

所以，这是我的 CMakeLists.txt：

cmake_minimum_required(VERSION 3.5)

project(TileGameStudio_Runtime CXX)

set(CMAKE_CXX_FLAGS -v)
set(CMAKE_VERBOSE_MAKEFILE ON)
set(CMAKE_INCLUDE_CURRENT_DIR ON)

)

set(CMAKE_RUNTIME_OUTPUT_DIRECTORY "${PROJECT_SOURCE_DIR}\\Game")
set(EXECUTABLE_OUTPUT_PATH "${PROJECT_SOURCE_DIR}\\Game")

set_target_properties(
    TileGameStudio_Runtime

        OUTPUT_NAME "Game"
        SUFFIX ".exe"

这是我的整个 main.cpp：

    SDL_Window *window = NULL;
    SDL_Renderer *renderer = NULL;

    SDL_Init(SDL_INIT_VIDEO);
    TTF_Init();

    SDL_GL_SetAttribute(SDL_GL_RED_SIZE,5);
    SDL_GL_SetAttribute(SDL_GL_GREEN_SIZE,5);

    uint32_t windowFlags = SDL_WINDOW_OPENGL;
    window = SDL_CreateWindow("Runtime",SDL_WINDOWPOS_CENTERED,WinWidth,WinHeight,windowFlags);
    assert(window);
    SDL_GLContext Context = SDL_GL_CreateContext(window);

    bool Running = true;
    bool FullScreen = false;
    while (Running)
    {
        SDL_Event Event;
        while (SDL_PollEvent(&Event))
        {
            if (Event.type == SDL_KEYDOWN)
            {
                switch (Event.key.keysym.sym)
                {
                case SDLK_ESCAPE:
                    Running = 0;
                    break;
                case 'f':
                    FullScreen = !FullScreen;
                    if (FullScreen)
                    {
                        SDL_SetWindowFullscreen(window,windowFlags | SDL_WINDOW_FULLSCREEN_DESKTOP);
                    }
                    else
                    {
                        SDL_SetWindowFullscreen(window,windowFlags);
                    }
                    break;
                default:
                    break;
                }
            }
            else if (Event.type == SDL_QUIT)
            {
                Running = 0;
            }
        }

        glViewport(0,WinHeight);
        glClearColor(0.f,0.f,0.f);
        glClear(GL_COLOR_BUFFER_BIT);

        SDL_GL_SwapWindow(window); //Update Window Context
    }
    return 0;
}

这是我现在的整个项目结构：

该项目无法找到并打开 lua.h。 （文件打不开）

安装的Luajit版本为：

mingw64/mingw-w64-x86_64-luajit 2.1.0_beta3-2 [installed]
    Just-in-time compiler and drop-in replacement for Lua 5.1 (mingw-w64)

这是cmake的输出：

解决方法

我为自己找到了答案。 错误似乎是随机出现的。重新启动Vscode 2-3次后，错误出现或不出现随机。好像是IDE的问题?
