#
# The script to detect Intel(R) Integrated Performance Primitives (IPP)
# installation/package
#
# By default, ICV version will be used.
# To use standalone IPP update cmake command line:
# cmake ... -DIPPROOT=<path> ...
#
# Note: Backward compatibility is broken, IPPROOT environment path is ignored
#
#
# On return this will define:
#
# HAVE_IPP - True if Intel IPP found
# HAVE_IPP_ICV - True if Intel IPP ICV version is available
# IPP_ROOT_DIR - root of IPP installation
# IPP_INCLUDE_DIRS - IPP include folder
# IPP_LIBRARIES - IPP libraries that are used by OpenCV
# IPP_VERSION_STR - string with the newest detected IPP version
# IPP_VERSION_MAJOR - numbers of IPP version (MAJOR.MINOR.BUILD)
# IPP_VERSION_MINOR
# IPP_VERSION_BUILD
