【问题描述】：
我遇到的问题是，当我运行“C++ 运行/调试活动文件”时，代码会执行，但不会在我设置的断点处停止。我不太了解调试器的工作原理，但我猜调试器没有听正确的进程？或者为什么会这样？
老实说，我一直在努力让我的所有依赖项都正确，并且在此过程中可能破坏了预期的功能，因此可能是我设置脚本的方式破坏了它的预期用途。

我重做了它，这次变慢了。我没有启动文件，但是

-
@AlanBirtles 抱歉，已更新
-
是的，这就是为什么我把它放在标签中，我应该把它放在标题中吗？
-
有趣的是，微软如何设法获得像“用 g++ 构建一些 C++ 源代码”这样简单且易于理解的东西，如此复杂并与他们的平台 (VSC) 相关联，以至于我看着这个烂摊子就走了“不，不会打扰”。 :-D
-
@DevSolar 哈哈，是的，我不是粉丝，我正在完成一个新项目，并以更慢的速度将其组合在一起，以确保我理解每一步并希望抓住我打破的东西
-
@DevSolar 是的，vscode 更像是一个美化的文本编辑器而不是一个 ide，但是使用正确的插件，一个 cmake 项目无需额外配置即可工作。其他项目通过不尝试从 vs 代码内部构建而仅使用它来调用外部构建系统来简化
