With the number of libraries in VTK 6, your life will be a lot easier
if you use CMake to configure you project.

VTK_USE_FILE is a CMake variable that points to a file that has
configuration information for using your VTK build. You don't add it
to your preprocessor definitions. Instead, if you were using CMake to
configure your project, the CMake "include" command would import the
configuration information in the VTK_USE_FILE.

Including the file pointed to by the VTK_USE_FILE variable in CMake,
the preprocessor definitions needed to get everything to work are
automatically added for you.

If you really do not want to move your project over to use CMake for
build configuration, then my advice would be to set up a small CMake
project that uses VTK and examine the compiler definitions that you
need to specify on the command line.
