CMake无法在Qt6安装中找到包
CMake无法在Qt6安装中找到包
提问于 2022-02-11 20:55:56
我正在尝试通过CMake构建一个项目，并将环境变量Qt6_DIR设置为包含Qt6Config.cmake的目录。但是，构建似乎无法在Qt6安装中找到它需要的任何其他依赖项&我不确定下一步需要做什么。我看到了对其他可能的环境变量的引用，比如"Qt6CoreTools_DIR“，我想知道我是否真的需要独立地设置这些变量，或者是否有一个包含这些信息的工具链需要正确地链接到。

"Qt6CoreTools" provides a separate development package or SDK, be sure it

将此添加到根cmake中。
list(APPEND CMAKE_PREFIX_PATH "~/Qt/6.3.0/gcc_64")根据需要更改路径。

根据QTBUG-97615，不支持使用单个Qt6_DIR配置构建，而配置应用程序构建的“正式”方法是使用CMAKE_PREFIX_PATH (如其他答案所建议的)。
但是，如果您的工具不容易支持这样的appoach (比如VisualStudio/VSCode)，那么这种情况是有解决办法的(我是在挖掘Qt6混乱的cmake脚本时发现的)。
QT_ADDITIONAL_PACKAGES_PREFIX_PATH 您可以使用来指定Qt根(以及Qt6_DIR最初将其挂起)。
命令行如下所示(只是为了说明方法)：
cmake -DQt6_DIR:PATH=C:/Qt6/6.2.3/mingw_64/lib/cmake/Qt6 -DQT_ADDITIONAL_PACKAGES_PREFIX_PATH=C:/Qt6/6.2.3/mingw_64 ..
这两个变量都很容易通过VisualStudio/VSCode中的UI进行配置。
幸福大厦！:)
