[vtkusers] VTK Debug setting on OS X

[Chris Scharver]

Hi,

I noticed that the OS X build doesn't set CMAKE_CXX_FLAGS_DEBUG and 
CMAKE_C_FLAGS_DEBUG by default. These should be set to -g. Another 
project using VTK couldn't set these variables because I did not 
originally them when I built VTK, so UseVTK.cmake was overriding 
them. I'm not sure if this would be a VTK change or a CMake default 
setting change for the OS X compiler, but it should probably be set 
in one of the two places.
