如何在Windows上findqt5 CMake模块

我试图在Windows上使用CMake制作一个非常基本的Qt5应用程序。 我使用qt5的文档来使用CMake ,而我的main.cpp文件只包含一个主函数。

我的CMakeLists.txt正是:

cmake_minimum_required(VERSION 2.8.9) project(testproject) 

编辑解决scheme

 set (CMAKE_PREFIX_PATH "C:\\Qt\\Qt5.0.1\\5.0.1\\msvc2010\\") 

结束编辑

 # Find includes in corresponding build directories set(CMAKE_INCLUDE_CURRENT_DIR ON) # Instruct CMake to run moc automatically when needed. set(CMAKE_AUTOMOC ON) # Find the QtWidgets library find_package(Qt5Widgets) # Tell CMake to create the helloworld executable add_executable(helloworld hello.cpp) # Use the Widgets module from Qt 5. qt5_use_modules(helloworld Widgets) 

当在MSysGit bash中input`$ cmake -G“Visual Studio 11”

我得到这个输出:

 $ cmake -G"Visual Studio 11" -- The C compiler identification is MSVC 17.0.60204.1 -- The CXX compiler identification is MSVC 17.0.60204.1 -- Check for working C compiler using: Visual Studio 11 -- Check for working C compiler using: Visual Studio 11 -- works -- Detecting C compiler ABI info -- Detecting C compiler ABI info - done -- Check for working CXX compiler using: Visual Studio 11 -- Check for working CXX compiler using: Visual Studio 11 -- works -- Detecting CXX compiler ABI info -- Detecting CXX compiler ABI info - done CMake Warning at CMakeLists.txt:11 (find_package): By not providing "FindQt5Widgets.cmake" in CMAKE_MODULE_PATH this project has asked CMake to find a package configuration file provided by "Qt5Widgets", but CMake did not find one. Could not find a package configuration file provided by "Qt5Widgets" with any of the following names: Qt5WidgetsConfig.cmake qt5widgets-config.cmake Add the installation prefix of "Qt5Widgets" to CMAKE_PREFIX_PATH or set "Qt5Widgets_DIR" to a directory containing one of the above files. If "Qt5Widgets" provides a separate development package or SDK, be sure it has been installed. CMake Error at CMakeLists.txt:17 (qt5_use_modules): Unknown CMake command "qt5_use_modules". -- Configuring incomplete, errors occurred! 

你有什么想法 ?

先谢谢你。

添加这个解决了这个问题。

set (CMAKE_PREFIX_PATH "C:\\Qt\\Qt5.0.1\\5.0.1\\msvc2010\\")

我编辑了第一篇文章。

您应该设置CMAKE_PREFIX_PATH环境变量,或者使用cmake-gui来设置Qt 5包的路径。

您只需要将Qt路径添加到Windows%PATH%变量。 正如在官方文档中所建议的: http : //doc.qt.io/qt-4.8/install-win.html#step-3-set-the-environment-variables

一种方法是在Qt Creator中打开CMakeLists.txt。 Qt Creator本身支持CMake,它总是知道Qt在哪里。
