Qt Project using cmake in CLion C++ - c++

Question

To be honest im not a fan of Qt Creator. So I decided to use another IDE like CLion. I researched and found out that Clion doesnt support qmake, but it is possible to get a Qt-Project to run with cmake.
Thats my CMakeList. CLion don't give me any error when i save this make-file.
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)
to test if it worked I created a simple cpp.
#include <iostream>
#include <QApplication>
using namespace std;
int main(int argc, char **argv)
{
QApplication app(argc,argv);
return app.exec();
}
I tried to implement it following these instructions
How to configure CLion IDE for Qt Framework?
I have to use the cmake binary that qt provides. So I set the Cmake Option to:
-DCMAKE_PREFIX_PATH=C:\Qt\Qt5.9.1\5.9.1\mingw53_32\lib\cmake
But if I try to compile it it gives me this error:
"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

I downloaded different versions of Qt because Qt 5.9 uses Mingw 5.3 and CLion says I'm using Mingw 5.0 and at the beginning I used Qt 5.6 and it used Mingw 4.9. I can't really figure out why it is not working.
A clean CMake Build looks like this
"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

Somehow there was no PATH to the Qt binary. I have added the PATH and rebuild the cmake Project and it worked. So it was just a matter of the path and of the versions.
