Distribute a Qt5 console application using CMake - c++

Question

I fruitlessly tried to distribute a basic Qt console application by using CMake.
Let's consider these 2 files:
main.cpp
#include <QDebug>
int main(int argc, char *argv[])
{
qDebug() << "Hello Wolrd!";
return 0;
}
CMakeLists.txt
cmake_minimum_required(VERSION 2.8.12)
project(HelloWorld)
set(CMAKE_AUTOMOC ON)
set(CMAKE_INCLUDE_CURRENT_DIR ON)
find_package(Qt5Widgets REQUIRED)
add_executable(${PROJECT_NAME} main.cpp)
qt5_use_modules(${PROJECT_NAME} Widgets)
Next I compile the main.cpp file doing:
$ cmake .

$ make
Scanning dependencies of target HelloWorld_autogen

[ 75%] Building CXX object CMakeFiles/HelloWorld.dir/main.cpp.o
[100%] Linking CXX executable HelloWorld
[100%] Built target HelloWorld
And I get a HelloWorld binary file.
The problem comes when I try to execute the latter file on another computer which don't have Qt installed. I get this bellow error:
dyld: Library not loaded: #rpath/QtWidgets.framework/Versions/5/QtWidgets
Referenced from: /path/to/HelloWorld/./HelloWorld
Reason: image not found
./test.sh: line 4: 68737 Abort trap: 6 ./HelloWorld
What is missing to make this working as a standalone application?
Environment:
MacOs Mojave (10.14.4)
Qt 5.10.1

The easiest approach is to link Qt statically. Check out the documentation about deploying for macOS.
Be aware that Qt is licensed under the LGPL, which may have implications for static linking. Check out this FAQ for details.
You could also use bundles and frameworks, but I'm not sure how well that works with console applications.
