The build docs specifically mention that our cmake installs shouldn't be "old", but it's only a lower limit at 3.15. But after I installed a fresh cmake v3.19.1, it failed the build saying something along the lines of:

in function 'exit': exit.c:(.text.exit+0x60): undefined reference to '_exit'

Tracked this to a related bug report where the consensus seemed to be that this is caused by cmake 3.19 (either 3.19.0 or 3.19.1). Downgrading to 3.18.5 did indeed help. This might be worth noting in the docs @mcrosson...
