automatically load settings from CMakeLists.txt

I love Qt and Qt loves CMake.

Inside my CMakeLists.txt I wrote

project(myAppName LANGUAGES CXX DESCRIPTION "My good app" VERSION 1.2.3.4)

I expect that setApplicationName will done automatically based on CMakeLists.txt The same for setApplicationVersion.

But for now I need dirty hack. Inside CMakeLists.txt

add_compile_definitions( -DMYPROJECT_NAME=${PROJECT_NAME} )

Inside main.cpp

#define Q(x) #x
#define QUOTE(x) Q(x)
QCoreApplication::setApplicationName(QUOTE(MYPROJECT_NAME));

With dirty hack I can use ${PROJECT_NAME} from CMakeLists.txt for setApplicationName. I suggest Qt automatically load settings from CMakeLists.txt. There is another method to export variables.
