# The build is really memory hungry (at least with gcc8), even with just -j 8 it triggers OOMK on system with 32GB ram
# High memory needs mentioned in: https://github.com/PointCloudLibrary/pcl/issues/2284
# Setting just empty doesn't work, ninja will by default use number of cores available
# However, quick experiments have shown that it's possible to use up to CEIL(<RAM-in-GB>/5) as the argument to -j without running
# out of memory as long as the machine has a few GB of swap spacce => override the setting here by setting
# PARALLEL_MAKE_pn-pcl in conf/local.conf .
PARALLEL_MAKE = "-j1"

# Fixes this:
# | fatal error: stdlib.h: No such file or directory
