When on Windows making a GUI application MFC (I think) has its own
special "main" instead of the normal "main" that everyone else uses.
Qt has an implementation of this and the If() statement below makes
sure that if you are on windows your program will link in this special
"main". If you don't use it then you will get link errors on windows.
If you _never_ will compile your program on Windows or you are just
making a console application then you can probably skip it.
All that is from memory and I am not a Windows Expert by any
stretch of the imagination.

Also BEFORE the FindPackage(Qt4) add the following line:
IF (WIN32)
SET (QT_USE_QTMAIN TRUE)
It works. But what's the meaning here?
I hope you can give me some links. I googled it, but
I can't find enough answers for me.
ENDIF (WIN32)
