Brad King 117e7e1177 FindVTK: Drop support for finding VTK 4.0
Convert to a simple thin-wrapper around the find_package(VTK NO_MODULE).
This makes the code much simpler and improves error messages.

# FindVTK
# -------
#
# Find a VTK installation or build tree.
#
# The following variables are set if VTK is found. If VTK is not found,
# VTK_FOUND is set to false.
#
# ::
#
# VTK_FOUND - Set to true when VTK is found.
#
# The following cache entries must be set by the user to locate VTK:
#
# ::
#
# VTK_DIR - The directory containing VTKConfig.cmake.
# This is either the root of the build tree,
# or the lib/vtk directory. This is the
# only cache entry.
#
# The following variables are set for backward compatibility and should
# not be used in new code:
#
# ::
#
# USE_VTK_FILE - The full path to the UseVTK.cmake file.
# This is provided for backward
# compatibility. Use VTK_USE_FILE
# instead.
