Brad King 38b0a84eea Modernize FindITK module (#11494)
Use the Config mode of find_package to search for ITKConfig.  This makes
FindITK a thin-wrapper around a standard find_package, bringing benefits
like searching lib64 paths when appropriate.  This does for FindITK what
commit 2c1a01dc (Modernize FindVTK module, 2009-10-07) did for FindVTK.

# - Find an ITK installation or build tree.
# When ITK is found, the ITKConfig.cmake file is sourced to setup the
# location and configuration of ITK. Please read this file, or
# ITKConfig.cmake.in from the ITK source tree for the full list of
# definitions. Of particular interest is ITK_USE_FILE, a CMake source file
# that can be included to set the include directories, library directories,
# and preprocessor macros. In addition to the variables read from
# ITKConfig.cmake, this find module also defines
# ITK_DIR - The directory containing ITKConfig.cmake.
# This is either the root of the build tree,
# or the lib/InsightToolkit directory.
# This is the only cache entry.
#
# ITK_FOUND - Whether ITK was found. If this is true,
# ITK_DIR is okay.
#
# USE_ITK_FILE - The full path to the UseITK.cmake file.
# This is provided for backward
# compatability. Use ITK_USE_FILE
# instead.
