Include Path

Hi,
I just have a simple question which bothers me a long time now.

If I open the Lyra Exampe, the include Path looks like

#include "Settings/LyraSettingsLocal.h"
...

Thus, Visual Studio finds the Files referenced in the Folder Source\LyraGame.

If I create a new Project, the inclusion does not work like that. my working options are

#include "../Settings/LyraSettingsLocal.h"         //Thus reference to the main folder
#include <LyraGame/...>

Can anyone tell me, what I’m doing wrong?
