我正在尝试为我的Manjaro靴子（一个Arch发行版）编译一个窗口装饰，并且出现此错误：

我相信问题与我拥有的qt版本有关，并且我安装了以下软件包：cmake extra-cmake-modules kdecoration qt5-declarative qt5-x11extras
This is the window decoration's github
我是否缺少包裹？是否有过期的包装或窗户装饰本身已过期？按照惯例，请告诉我是否缺少您需要帮助的重要信息。谢谢！
客户端方法返回一个QWeakPointer，该QWeakPointer具有用于访问指针的data()方法，但现在已弃用，解决方案是更改：
data()to
foo->client().data()
我已经创建了应用该更改的项目的foo->client().toStrongRef().data()
，因此您可以使用它：
fork
或将以下修补程序应用于原始存储库：
git clone https://github.com/eyllanesc/material-decoration-bt.git
cd material-decoration-bt; bash setup.sh
