# To enable the Instrumentation and Tracing Technology API (ittnotify):
#   - install the package intel-seapi
#   - in build(), change '-DENABLE_ITT:BOOL=' from 'OFF' to 'ON'
#   - and then build intel-media-sdk
# intel-seapi will be autodetected by the build system, serving as a makedepend.
# Currently it will not be a mandatory makedepend.
