Thank you, nice improvement. I tried, it works. I was not far,
MAKEOPTS="-j1" was part of what I tried. Found some inspiration there,
where a known bug leads to build doxygen's own documentation with "-j1".
https://gitweb.gentoo.org/repo/gentoo.git/tree/app-text/doxygen/doxygen-1.13.2.ebuild
It seems that the default `DOT_NUM_THREADS = 0` has a mind of its own
and ignores MAKEOPTS. Your case is with cmake, with a non-obvious build
option (glanced at the source of cmocka, I don't know where that switch
comes from). This here is with meson, I don't know of a magic mechanism
for that.

Don't they offer any upstream source for a pre-built PDF, or could you
find one?
It's an interesting problem. If I didn't find it interesting,
downloading a pdf would be a good idea, better than "won't build,
problems, I have nothing".
