2 compilation questions

[Uwe Stöhr]

- we store our frontends files in a folder named qt4. Should we split it 
up to qt5 and qt4 to address specific changes? If not we can rename the 
folder to just "qt", right?

- I could now compile the dependencies with MSVC. Thus also libintl. But 
in CMake I cannot see that libintl is actually used. Is this correct and 
we can get rid of it?

thanks and regards
Uwe
