我正在学习使用 KDE 框架的介绍性教程，但在编译时遇到了问题。代码与教程中的相同。编译器输出：
fatal error: KXmlGuiWindow: No such file or directory
我的第一个想法是我只是缺少一个包，所以我使用 apt-cache search 来搜索 kxml 并安装了 libkf5xmlgui-dev。尽管错误仍然存在。我无法在网上任何地方引用此错误。导入路径是否更改？是否需要另一个包裹？
我正在运行 Kubuntu 20.04。
我以前必须安装其他软件包来编译尚未包含 KXmlGuiWindow 的“Hello World”程序，但是当我安装它们后一切正常。
编辑：
find /usr -name KXmlGuiWindow给了我输出/usr/include/KF5/KXmlGui/KXmlGuiWindow。我将 Atom 用于我的代码编辑器，因此我通过运行教程中给出的命令cmake .. && make（从项目根目录中的构建目录）从终端编译程序。
该命令的完整输出 pf 是

添加标志解决了其中一个错误，即原始帖子中提到的错误。我仍然遇到其他错误，但我会先寻找现有的解决方案。
