[vtkusers] Migration to VTK6

David --

There was no instance of "AGL" in CMakeCache.txt, but I replaced every
instance of "AGL" with OpenGL" in all of the build.make files.  Without
cmake, but with make I got the following error:

make[2]: *** No rule to make target
`/Applications/Xcode.app/Contents/Developer/Platforms/MacOSX.platform/Developer/SDKs/MacOSX10.7.sdk/System/Library/Frameworks/OpenGL.framework',
needed by `travel_depth/TravelDepthMain'.  Stop.

It still calls 10.7 even though I have 10.11 installed on my Mac.

Cheers,
@rno
