# 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
