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.

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".
