## Qt projects ##

[Qt][] is a cross-platform C++ framework for creating GUI applications. Qt uses its own build system, [qmake][], and also supports [building with CMake][] starting from the version Qt4.

Qt是一款创建桌面程序的跨平台的C++框架。qmake是Qt自有的构建系统，从Qt4版本开始，Qt系统开始支持CMake进行构建。

A pure Qmake project can't be imported in CLion directly. However, when converted into CMake, it can be opened and managed as a regular [CMake application][]. You can also [create a CMake-based Qt project][] in CLion using the New Project wizard.

CLion无法直接引入由qmake创建的项目，但是可以打开从qmake转换成cmake的Qt项目。开发人员也可以通过CLion的工程向导创建基于CMake的Qt工程。

## CMake-based Qt projects ##

For CMake version 3.0 and newer, Qt ships the modules that let CMake find and use Qt4 and Qt5 libraries. Take the following steps to configure [CMakeLists.txt][] for your Qt project.

对于CMake 3.0及更新版本，CMake 查找Qt模块并使用 Qt4 和 Qt5 库。请按以下步骤为您的 Qt 项目配置 CMakeLists.txt。

### CMakeLists.txt for a Qt project ###

Qt项目的CMakeList.txt文件

*  Add the `find_package` command to locate the required libraries and header files. For example:

添加find\_package命令定位查找所需的库文件和头文件，例如：

find_package(Qt5Widgets REQUIRED)

Then, use `target_link_libraries` to make your target dependent on these libraries and headers:

随后，使用`target_link_libraries`命令将你的目标绑定查找到的库文件和头文件。

target_link_libraries(helloworld Qt5::Widgets)

*  For `find_package` to perform successfully, CMake should be instructed on where to find the Qt installation.

当find\_package命令运行成功后，接下来给CMake配置Qt的安装配置。

One of the ways to do this is by setting the `CMAKE_PREFIX_PATH` variable. You can either pass it via `-D` in the [CMake settings][] dialog or via the `set` command before `find_package`.

一种方式是通过给CMake设定`CMAKE_PREFIX_PATH`变量。这种设定方式既可以通过在CMake的设置对话框中传入“-D”或者在find\_package命令之前通过set命令设置。

For example, in the case of MinGW on Windows:

例如，在Windows系统中设置MinGW：

set(CMAKE_PREFIX_PATH "C:\\Qt\\Qt5.14.0\\5.14.0\\mingw73_32\\")

或者

set(CMAKE_PREFIX_PATH "C:\\Qt\\Qt5.14.0\\5.14.0\\mingw73_32\\lib\\cmake\\")

*  If your project uses [MOC][], [UIC][], or [RCC][], add the following lines to enable automatic invocation of the corresponding compilers:

如果项目中使用到MOC、UIC或者RCC，请添加以下命令启动相应的编译器：

set(CMAKE_AUTOMOC ON)
    set(CMAKE_AUTOUIC ON)
    set(CMAKE_AUTORCC ON)

*  List all the .ui and .qrc files in the `add_executable()` command along with your .cpp sources:

在add\_executable()命令列出你的“.cpp”文件、“.ui”文件和“.qrc”文件。

add_executable(
        helloworld
        main.cpp mainwindow.cpp
        application.qrc
    )

Below you can find the full CMakeLists.txt script for a simple "Hello, world" application:

下面列出了“Hello, world”程序所需的CMakeList.txt脚本：

cmake_minimum_required(VERSION 3.10)
    project(Qt-CMake-HelloWorld)
    
    set(CMAKE_CXX_STANDARD 17)
    set(CMAKE_INCLUDE_CURRENT_DIR ON)
    set(CMAKE_PREFIX_PATH "C:\\Qt\\Qt5.14.0\\5.14.0\\mingw73_32\\")
    
    find_package(Qt5Widgets REQUIRED)
    
    set(CMAKE_AUTOMOC ON)
    set(CMAKE_AUTOUIC ON)
    set(CMAKE_AUTORCC ON)
    
    add_executable(helloworld main.cpp mainwindow.cpp application.qrc)
    target_link_libraries(helloworld Qt5::Widgets)
