Question

使用CMake构建文件时出现以下错误：

CMake Warning at CMakeLists.txt:33 (FIND_PACKAGE):

By not providing "FindQt5Core.cmake" in CMAKE_MODULE_PATH this project has
  asked CMake to find a package configuration file provided by "Qt5Core", but
  CMake did not find one.

  Could not find a package configuration file provided by "Qt5Core" with any of the following names:

    Qt5CoreConfig.cmake
    qt5core-config.cmake

有谁知道如何解决这个问题？提前致谢

Answer 1

您应该在Qt安装中找到cmake包：

<install_prefix>/lib/cmake

假设<install_prefix>是您安装的根路径。在配置中将变量Qt5_DIR设置为<install_prefix>/lib/cmake/Qt5，cmake应该能够找到所有模块

Answer 2

也许，您应该尝试在环境或配置中添加CMAKE_PREFIX_PATH变量的正确路径。

export CMAKE_PREFIX_PATH=path_to/Qt/5.9/clang_64:$CMAKE_PREFIX_PATH

将path_to替换为您的真实路径。

Answer 3

此错误消息的一个可能原因是过时的CMake代码，例如[1]

find_package(Qt5Core REQUIRED).

然后有一个很好的机会通过更改为

来解决问题

find_package(Qt5 COMPONENTS REQUIRED Core).

Answer 4

很多时候足以正确设置PATH环境变量，因此在终端中键入qmake时，它将执行正确的文件。有了它后，在命令行中执行cmake
