Even on my nuc with only 2 cores, setting "-j2" cuts the build time in half.

Albert-- I'm suspicious whether it's even building Gem:

https://git.purrdata.net/jwilkes/purr-data/-/jobs/22545/raw

Where's the log of that slow, plodding libtool compilation that
usually looks like this:

make[6]: Entering directory
'/home/user/builds/jwilkes/purr-data/Gem/src/Controls'
  CXX      libControls_la-gemframebuffer.lo
  CXX      libControls_la-gemcubeframebuffer.lo
  CXX      libControls_la-gemhead.lo


Also, I see this make message:

make[6]: Entering directory '/builds/jwilkes/purr-data/Gem/src/Controls'
UNUSED SOURCES in .: libControls_la-gemhead.o
libControls_la-gemcubeframebuffer.o libControls_la-gemlist_info.o
libControls_la-gemlist_matrix.o libControls_la-gemmanager.o
libControls_la-gemreceive.o libControls_la-gemframebuffer.o
libControls_la-render_trigger.o libControls_la-gemlist.o
libControls_la-modelfiler.o

Unfortunately, I can't be sure because Gem isn't hooked up to the
external creation tests yet.

Anyhow, are you seeing build times cut in half by this optimization?
