Subject: [PATCH] FindITK: Drop this ancient compatibility module

The FindITK module only existed to help find_package(ITK) calls work in
old projects written to use "USE_ITK_FILE" instead of "ITK_USE_FILE".
Drop it to allow find_package(ITK) calls to search for ITKConfig.cmake
directly.

+FindITK
+-------
+
+This module no longer exists.
+
+This module existed in versions of CMake prior to 3.1, but became
+only a thin wrapper around ``find_package(ITK NO_MODULE)`` to
+provide compatibility for projects using long-outdated conventions.
+Now ``find_package(ITK)`` will search for ``ITKConfig.cmake``
+directly.

-# FindITK
-# -------
-#
-# 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
-#                 compatibility.  Use ITK_USE_FILE
-#                 instead.
