Apparently he moved the SFML headers in the PySFML directory. What is strange is that apparently Graphics.hpp was found, but not Window.hpp.
Anyway, you should install the SFML headers (include/*) and libraries (lib/*) in the appropriate directories so that Visual Studio automatically recognizes them.
Apparently, the makefile generated by Cmake has an “install” target, so maybe you can use that, i.e. type “make install” in the console.
