Problem: vs2015 compiles vtk8.2 with an error    Error c2065 undeclared identifier error (__ func__）

Solution: (two)

(1) Change the header file sequence online (the first method is tested, but it doesn’t work. It’s here temporarily, and the second method is effective)

#include "StdAfx.h"

Put it first

(2) Change,, name (test valid)

__func__ replace to __FUNCTION__

Test valid
