c++ - CMake将Qt运行时库复制到可执行输出路径

问题描述

这个问题是重复的。但是，在筛选其他帖子后，我仍然无法解决问题。我的问题：尝试打包我的应用程序时，所以在我运行 cpack 后，运行时依赖项Qt5Core.dll, Qt5Gui.dll, Qt5Network.dll, Qt5Svg.dll, Qt5Widgets.dll放在目录的根目录中，而可执行文件和其余依赖项位于 bin 文件夹中。

就像我知道的那样，我可以将 bin 文件夹的内容复制到根目录之外，它会起作用，但就像不一样。

我的怀疑不确定，但我相信这个问题来自使用include(GNUInstallDirs). 如果有人可以提供解释和解决方案。谢谢

尝试运行可执行文件时出现错误消息。

This application failed to start because no Qt platform plugin could be initialized! Reinstalling the application may fix this problem.
