Question

说实话，我不是Qt Creator的粉丝。所以我决定使用像CLion这样的另一个IDE。我研究并发现Clion不支持qmake，但是有可能让Qt-Project与cmake一起运行。

这是我的 CMakeList 。保存这个make文件时，CLion不会给我任何错误。

cmake_minimum_required(VERSION 3.8)
project(Qt_CmakeTest)

set(CMAKE_CXX_STANDARD 11)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")
set(SOURCE_FILES main.cpp)
find_package(Qt5Core REQUIRED)
find_package(Qt5Widgets REQUIRED)
add_executable(Qt_CmakeTest ${SOURCE_FILES})
target_link_libraries(Qt_CmakeTest Qt5::Core Qt5::Widgets)

测试它是否有效我创建了一个简单的cpp。

#include <iostream>
#include <QApplication>

using namespace std;
int main(int argc, char **argv)
{
    QApplication app(argc,argv);
    return app.exec();
}

我尝试按照这些说明实施它 How to configure CLion IDE for Qt Framework?

我必须使用qt提供的cmake二进制文件。所以我将Cmake选项设置为：

-DCMAKE_PREFIX_PATH=C:\Qt\Qt5.9.1\5.9.1\mingw53_32\lib\cmake

但如果我尝试编译它会给我这个错误：

"C:\Program Files\JetBrains\CLion 2017.2.2\bin\cmake\bin\cmake.exe" --build 
C:\Users\Marcel\Desktop\Projekte\Qt\Qt-CmakeTest\cmake-build-debug --target Qt_CmakeTest -- -j 2

我下载了不同版本的Qt，因为Qt 5.9使用的是Mingw 5.3，而CLion说我使用的是Mingw 5.0，在开始时我使用的是Qt 5.6，它使用的是Mingw 4.9。我无法弄清楚它为什么不起作用。

干净的CMake Build看起来像这样

不知何故，Qt二进制文件没有PATH。我已经添加了PATH并重建了cmake Project并且它工作正常。所以这只是路径和版本的问题。

Qt Project在CLion C ++中使用cmake
