Unable to link CLion to QT On Windows 10

Im trying to link Qt Creator to Clion so i can use it for creating GUI elements but the only information I was able to find on doing this was this thread

How to configure CLion IDE for Qt Framework?

I tried to follow this as closely as possible but one of the major differences is that on windows there is no clang_64 file instead it is msvc2017_64 and that is what seems to be showing up in the error im getting.

My CmakeLists.txt

cmake_minimum_required(VERSION 3.5)
project(helloqt)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}")

set(SOURCE_FILES main.cpp)
find_package(Qt5Widgets REQUIRED)

add_executable(helloqt ${SOURCE_FILES})

target_link_libraries(helloqt Qt5::Widgets)

my main.cpp

#include <QApplication>
#include <QDebug>

using namespace std;

int main() {
    qDebug() << QT_VERSION_STR;
    return 1;
}

under Settings>Build, Execution, Deployment > CMake my Cmake Options has the path

-DCMAKE_PREFIX_PATH=C:/Qt/5.12.1/msvc2017_64/lib/cmake

and it results in this error which I have not been able to find a fix to.

It can't find symbol like QMessageLogger which is part of Qt Core. Note you have used qDebug() which refers to this symbols!

Conclusion is simple add this to your CMakeLists.txt:

find_package(Qt5Core REQUIRED) # this might be not needed
target_link_libraries(helloqt Qt5::Widgets Qt5::Core) 

Offtopic: trash this:

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS}")

since it doesn't do anything.
