# Set the 'threads' variable to the computer's # of cpu threads+1
threads=`expr \`cat /proc/cpuinfo |grep -i 'core id'|wc -l\` \+ 1`
# then use 'make -j' option to compile all software (e.g. make -j9 on an 8-thread CPU)
# e.g., make -j$threads

# Prerequisites:
# - See: http://scigeo.org/articles/howto-install-latest-geospatial-software-on-linux.html#gdal
