cmake/Modules/FindITK.cmake

# - 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.
