# Find the native VTK includes and library
#
# This module defines:
#
# VTK_INSTALL_PATH - Where is the installed version of VTK.
# USE_BUILT_VTK - Should a built-from-source version of VTK be used.
#
# VTK_BINARY_PATH - Where is (one of) the binary tree(s).
# USE_INSTALLED_VTK - Should an installed version of VTK be used
#
# USE_VTK_FILE - (internal)
# Full path and location to the UseVTK.cmake file.
# This value changes each time USE_BUILT_VTK or
# USE_INSTALLED_VTK is modified, and only if ONE of
# these setting is set to ON.
#
# If VTK is not found, an error is displayed unless VTK_FIND_QUIETLY
# is on.
#
#
# Look for a binary tree (built from source)
