C++ Question

Using Qt inside Clion

I'm trying to use Clion IDE to compile a simple program using Qt library, but I can't figure out how to configure

CMakeLists.txt
file. (I'm not familiar with cmake and toolchain)
this is my current
CMakeLists.txt
file:

cmake_minimum_required(VERSION 3.2)
project(MyTest)

set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -std=c++11")

set(SOURCE_FILES main.cpp)
add_executable(MyTest ${SOURCE_FILES})

# Define sources and executable
set(EXECUTABLE_NAME "MySFML")
add_executable(${EXECUTABLE_NAME} main.cpp)



# Detect and add SFML
set(CMAKE_MODULE_PATH "${CMAKE_SOURCE_DIR}/cmake_modules" ${CMAKE_MODULE_PATH})
find_package(SFML 2 REQUIRED system window graphics network audio)
if(SFML_FOUND)
include_directories(${SFML_INCLUDE_DIR})
target_link_libraries(${EXECUTABLE_NAME} ${SFML_LIBRARIES})
endif()


It's configured to use SFML library with a "FindSFML.cmake" file and it works fine. (I have copied these files from some tutorial) now I want some help regarding proper
CMakeLists.txt
configuration to compile programs that are using Qt library (it's more helpful if the files and explanations are provided).




P.S: my current OS is manjaro 0.8.13 and all I could find was explaining configurations in windows environment so I was unable to implement those tutorials.

Answer

Your CMake project file is missing the Qt packages. You have to add:

find_package( Qt5Core REQUIRED )
find_package( Qt5Widgets REQUIRED )
find_package( Qt5Gui REQUIRED )

and then

qt5_use_modules( MyTest Core Widgets Gui )
