There are 23 of the former, and 27 of the latter.  I guess the latter is better, being both more descriptive and more numerous.  Shall I make a find/replace patch?

Alas, I have no CMakeLists file to to that in.

Neither VTKGL2 nor VTK_OPENGL2 are exported in any public .h file.  Would it be reasonable to #define it in vtkConfigure.h?
