*SOLVED* STL inludes error after SFGUI include?

[intrinsic]

I'm using VS2015 and I wanted to start playing around with SFGUI. So I added its include files to my SFML Project.
After adding the include folder and lib folder to the VC++ directories I get errors in my code.
Like "cannot open source file "vector"" and also an error with sf::RenderWindow not having matching params.

So i removed SGUI from the VC++ directories and I still can't compile.
Has anyone encountered this issue before?

EDIT: I found the problem, i had to check the "Inherent from parent or project defaults" check box.
