#
# The script to detect Intel(R) Integrated Performance Primitives (IPP)
# installation/package
#
# This will try to find Intel IPP libraries, and include path by automatic
# search through typical install locations and if failed it will
# examine IPPROOT environment variable.
# Note, IPPROOT is not set by IPP installer, it should be set manually.
#
# On return this will define:
#
# IPP_FOUND - True if Intel IPP found
# IPP_ROOT_DIR - root of IPP installation
# IPP_INCLUDE_DIRS - IPP include folder
# IPP_LIBRARY_DIRS - IPP libraries folder
# IPP_LIBRARIES - IPP libraries names that are used by OpenCV
# IPP_LATEST_VERSION_STR - string with the newest detected IPP version
# IPP_LATEST_VERSION_MAJOR - numbers of IPP version (MAJOR.MINOR.BUILD)
# IPP_LATEST_VERSION_MINOR
# IPP_LATEST_VERSION_BUILD
