*** build.sh by default will launch parallel compile jobs depending on the available CPU cores,
e.g. 4 jobs on a modern hyperthreaded dual-core processor.
but
when building on a virtual machine/server or other limited environment,
reduce the jobs by passing a number,
e.g ./build.sh --jobs 1 to set only one compile job at a time.
