CMake 将 Qt 运行时库复制到可执行输出路径

Question

这个问题是重复的。但是，在浏览了其他帖子后，我仍然无法解决问题。我的问题：当尝试打包我的应用程序时，所以在我运行 cpack 之后，运行time 依赖项 Qt5Core.dll, Qt5Gui.dll, Qt5Network.dll, Qt5Svg.dll, Qt5Widgets.dll 被放置在目录的根目录中，而可执行文件和其余依赖项是在 bin 文件夹中。

据我所知，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。

Answer 1

您在

中使用DESTINATION .明确要求您的结果

    install(
        DIRECTORY ${CMAKE_BINARY_DIR}/qtDeploy/
        DESTINATION .
        FILES_MATCHING PATTERN "*.*"
    )

这可能是 DESTINATION ${CMAKE_INSTALL_BINDIR} 指向您用于其他二进制文件的同一目录。
