find_package(Qt5Core REQUIRED)

# Create a list with all .cpp source files
set( project_sources
   main.cpp
   hello.cpp
)

# Create executable with all necessary source files
add_executable(${PROJECT_NAME}
  ${project_sources}
)

qt5_use_modules( ${PROJECT_NAME} Core )

main.cpp:

#include 
#include "hello.h"

using namespace std;

int main()
{
    Hello H;
    H.say();
    cout <<"Hello World!" <

#ifndef HELLO_H

   Hello();
   void say();
};

#endif // HELLO_H

#include 
#include "Hello.h"

Hello::Hello()

void Hello::say()
{
   std::cout <<"Hello from hello class!" <
