在CLion C++中使用cmake的Qt項目

說實話，我不是Qt Creator的粉絲。所以我決定使用另一個像CLion的IDE。我研究並發現Clion不支持qmake，但可以通過cmake運行Qt-Project。我的CMakeList。當我保存這個make-file時，CLion不會給我任何錯誤。在CLion C++中使用cmake的Qt項目

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)

來測試它是否工作我創建了一個簡單的cpp。

#include <iostream> 
#include <QApplication> 

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

我試圖實現它以下說明 How to configure CLion IDE for Qt Framework?

我必須使用CMake的二進制文件Qt提供。所以我設置CMake的期權：

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

但是，如果我嘗試編譯它，它給了我這個錯誤：

"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

我下載不同版本的Qt的，因爲Qt的5.9使用MinGW的5.3和CLion說我使用的是Mingw 5.0，一開始我使用的是Qt 5.6，它使用了Mingw 4.9。我無法弄清楚爲什麼它不起作用。

乾淨CMake的構建是這樣的

"C:\Program Files\JetBrains\CLion 2017.2.2\bin\cmake\bin\cmake.exe" -DCMAKE_BUILD_TYPE=Debug -G "CodeBlocks - MinGW Makefiles" C:\Users\Marcel\Desktop\Projekte\Qt\Qt-CmakeTest

你鏈接到'Qt5 :: Widgets'，但你似乎也需要鏈接到'Qt5 :: Core'。 – nwp

更新了CMakeList。還是行不通。還嘗試設置路徑（CMAKE_PREFIX_PATH「C：/Qt/Qt5.9.1/5.9.1/msvc2017_64」）並嘗試了不同的版本（VS，mingw） – MNCODE

錯誤消息是否完全改變？你有沒有試圖找出Qt可能需要的其他庫？ – nwp

不知怎的，沒有路徑Qt的二進制文件。我已經添加了PATH並重建cmake項目，它工作。所以這只是路徑和版本的問題。
