# This is required on Ubuntu 18; the new linker behaviour transforms
# RPATH into RUNPATH (which can be seen in the output of 'readelf -d').
# However, RUNPATH does not work recursively, so when OpenVINO reads
# the plugins.xml file and searches for the specified libcoreDlaRuntimePlugin.so
# library, it fails. The --disable-new-dtags option causes the linker
# to keep RPATH as RPATH (rather than morphing to RUNPATH).

# The solution below seems preferable to setting LD_LIBRARY_PATH, if only barely.
# For additional motivation, go ahead and throw away part of your day reading either
# of the screeds:
# http://xahlee.info/UnixResource_dir/_/ldpath.html
# https://gms.tf/ld_library_path-considered-harmful.html
# You may find that neither is fully convincing, of course.
