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"

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.
