[vtkusers] vtk6 porting question (segfault)

Tue Aug 14 16:51:21 EDT 2012

That sounded wrong. I'm fully aware that CMake is a great way to write
portable applications. What I mean I guess is a simpler way to write simple
applications that use VTK > 5.8, avoiding the need to use $VTK_LIBRARIES.
Or is there a way to make CMake set $VTK_LIBRARIES as an environmental
variable so other build processes can use it?

Thanks,

-- Trevor
