c++ - 如何调试 CMake 项目中缺少的标头？
问题描述
我应该遵循什么通用算法来调试诸如此类的问题？

示例项目同时使用 Qt (Quick 2) 和 Magnum，这两个库都广泛使用了 OpenGL。当我分别为它们启动示例项目时，它们都运行良好并且构建没有错误。当我试图嫁给他们时，它就失败了。
那么在这种情况下要遵循什么程序呢？如何找出这些 ( glFlush) 声明丢失的原因？我尝试添加find_package(OpenGL....到我的项目中，但没有成功。我感兴趣的是找出问题所在的过程，而不是解决这个特定问题的方法。
谢谢你这么
更新：这里的 CMake 文件https://gist.github.com/skrat/c5b20d6753e6476a4a0d60227cb73cda
在包含 Magnum 之前，我有相同的项目，我在其中包含find_package(OpenGL...并能够成功使用原始 OpenGL 调用。在一个单独的 Magnum 唯一项目中，我不必找到 OpenGL 包，一切都很好，我假设 Magnum 的 CMake 文件完成了艰苦的工作。
