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.
