Question

我在使用 CMake 时遇到了一些问题。当我尝试为 Visual Studio 2019 配置我的构建时，它向我显示一个错误。当我检查 CMakeLists.txt 时，一切看起来都很好，但仍然有问题。该文件是由 Qt 自动创建的，我只是添加了一些东西来连接一些目录。我该怎么做才能解决这个问题？

这里是错误：

CMake Error at CMakeLists.txt:27 (find_package):
  Could not find a package configuration file provided by "QT" with any of
  the following names:

    Qt6Config.cmake
    qt6-config.cmake
    Qt5Config.cmake
    qt5-config.cmake

  Add the installation prefix of "QT" to CMAKE_PREFIX_PATH or set "QT_DIR" to
  a directory containing one of the above files.  If "QT" provides a separate
  development package or SDK, be sure it has been installed.


Configuring incomplete, errors occurred!

这是我的 CMakeList.txt：

添加 set(CMAKE_PREFIX_PATH "/Users/YOURPATH/Qt/6.1.0/clang_64") find_package(QT NAMES Qt6 Qt5 COMPONENTS Widgets REQUIRED)之前的这行代码为我解决了这个问题（macOS）。找到QT目录，复制/clang_64文件的路径。如果您在使用 QT 时遇到问题，请尝试重新安装 https://www.qt.io/download-open-source?hsCtaTracking=9f6a2170-a938-42df-a8e2-a9f0b1d6cdce%7C6cb0de4f-9bb5-4778-ab02-bfb62735f3e5
