如何在 Windows 上找到 Qt5 CMake 模块

  
本文介绍了如何在 Windows 上找到 Qt5 CMake 模块的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！

问题描述

我正在尝试在 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 使用 CMake，而我的 main.cpp 文件只包含一个 main 函数.

I'm trying to make a very basic Qt5 application using CMake on Windows. I used the documentation of Qt5 to use CMake, and my main.cpp file just contains a main function.

我的 CMakeLists.txt 正是:

cmake_minimum_required(VERSION 2.8.9)

project(testproject)

# 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)

当我在 MSysGit bash 中输入

When in MSysGit bash I enter

$ 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

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!

你有什么想法吗?

推荐答案

行后

cmake_minimum_required(VERSION 2.8.9)

project(testproject)

添加

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

这就解决了问题.
