# The script detects Intel(R) Inference Engine installation
#
# Cache variables:
# INF_ENGINE_RELEASE - a number reflecting IE source interface (linked with OpenVINO release)
#
# Detect parameters:
# 1. Native cmake IE package:
# - environment variable InferenceEngine_DIR is set to location of cmake module
# 2. Custom location:
# - INF_ENGINE_INCLUDE_DIRS - headers search location
# - INF_ENGINE_LIB_DIRS - library search location
# 3. OpenVINO location:
# - environment variable INTEL_OPENVINO_DIR is set to location of OpenVINO installation dir
# - INF_ENGINE_PLATFORM - part of name of library directory representing its platform
#
# Result:
# INF_ENGINE_TARGET - set to name of imported library target representing InferenceEngine
#
