Cmake Can´t find luajit packages of msys2 (windows)

I got another Problem with including libs into my cmake Project. The Project specs are:

IDE: Visual Studio Code

Kit: GCC 10.3.0 Mingw64 (via msys2)

The two packages, Freetype and Luajit, are installed via msys (in mingw64 mode), too.

So, this is my 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)

list(APPEND CMAKE_MODULE_PATH "${CMAKE_CURRENT_SOURCE_DIR}/cmake")

set(PROJ_SRC
    ${PROJECT_SOURCE_DIR}/src
)

file(GLOB PROJECT_SOURCES CONFIGURE_DEPENDS
    ${PROJ_SRC}/*.cpp
)

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

if(NOT FREETYPE_FOUND)
  message(STATUS "freetype2:   NO")
else()
  message(STATUS "freetype2:   YES..   Version:${FREETYPE_VERSION_STRING}")
endif()

if(NOT LUA_FOUND)
  message(STATUS "LuaJit:   NO")
else()
  message(STATUS "LuaJit:   YES..   Version:${LUA_VERSION_MAJOR }  and Patched: ${LUA_VERSION_PATCH }")
endif()

include_directories(
    ${SDL2_INCLUDE_DIRS}
    ${SDL2_IMAGE_INCLUDE_DIRS}
    ${SDL2_TTF_INCLUDE_DIRS}
    ${SDL2_MIXER_INCLUDE_DIRS}

    ${LUA_INCLUDE_DIR}

)

# add the executable
add_executable(TileGameStudio_Runtime
    ${PROJECT_SOURCES}

)

set_target_properties(
    TileGameStudio_Runtime
    PROPERTIES
        OUTPUT_NAME "Game"
        SUFFIX ".exe"
)

And this, is my whole main.cpp:

    uint32_t windowFlags = SDL_WINDOW_OPENGL;
    window = SDL_CreateWindow("Runtime", SDL_WINDOWPOS_CENTERED, 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':

                    else
                    {
                        SDL_SetWindowFullscreen(window, windowFlags);
                    }
                    break;
                default:
                    break;
                }
            }
            else if (Event.type == SDL_QUIT)
            {
                Running = 0;
            }
        }

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

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

And this, is my whole Project Structure for now:

1

The Project is not able to find and open lua.h. (file can not be opened)

The installed Luajit Version is:

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)

And this is the cmake output:

Solution

  • I found an Answer for myself. It seems like the Errors appear randomly. After relaunching Vscode 2-3 times, the errors appear or do not appear randomly. Seems like a problem with the IDE 😐
