[wxVTK] still problems on MAC

[genesy g. <ge...@gm...>]

I tried the latest version (the Rez attempt) you committed but nothing
is changed.
When I launch the wxSample application I see  a grey window and nothing else.
Any Idea ? :-)

p.s. there is a typo in the CMakeList file:  the lines referring to
SRCS_VTKNotebook  have been stripped.
