该技术栈的部署过程分三步：

构建---编译---运行

构建：

bash 复制代码

cmake -S . -B build -G "Visual Studio 16 2019" -A x64 -DCMAKE_PREFIX_PATH="D:\Qt5_15\5.15.2\msvc2019_64\lib\cmake"

编译：

bash 复制代码

cmake --build build --config Debug

bash 复制代码

cmake --build build --config Release

运行：

bash 复制代码

.\build\Debug\QtSnake.exe

或者在文件夹中找的exe文件进行运行。

其中遇到的问题：

bash 复制代码

Automatic MOC for target QtSnake
  
  AutoMoc error
  -------------
  "SRC:/model.cpp"
  contains a "Q_OBJECT" macro, but does not include "model.moc"!
  Consider to
    - add #include "model.moc"
    - enable SKIP_AUTOMOC for this file

我在CMakeLists.txt 中配置了set(CMAKE_AUTOMOC ON) ，按道理mod工具会自动去链接mod文件，但是却没有构建成功。

解决：原因是我将.cpp .h .main写在了一起，当我分开之后就没有这个问题
