FindElastix.cmake

# - Find an elastix installation or build tree.

# When elastix is found, the ElastixConfig.cmake file is sourced to setup the
# location and configuration of elastix.  Please read this file, or
# ElastixConfig.cmake.in from the elastix source tree for the full list of
# definitions.  Of particular interest is ELASTIX_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
# ElastixConfig.cmake, this find module also defines
#  Elastix_DIR  - The directory containing ElastixConfig.cmake.
#                 This is either the root of the build tree,
#                 or the lib/elastix directory.
#                 This is the only cache entry.
#
#  ELASTIX_FOUND - Whether elastix was found.  If this is true,
#                  Elastix_DIR is okay.
#
#  USE_ELASTIX_FILE - The full path to the UseElastix.cmake file.
#                     This is provided for backward
#                     compatibility.  Use ELASTIX_USE_FILE
#                     instead.
