Only declare the variable in the header and in any other cpp that needs it use extern
That is backwards. The AP posted the correct solution. You have the variable screen defined in two places. Just define it in one or the other. The "extern" declaration in the Globals.h will take care of declaring it wherever else it may be used.
BTW, globals are evil, but globals.h and globals.cpp are even more evil.
