I'm able to reproduce the build failure in a non-Debian build on my
local machine with -j16. I can confirm that this is due to a race
condition in the build. The generated source file is created three times
in parallel by different make threads, and one of those threads tries to
compile it while another thread is in the middle of rewriting it.
Based on some info in the cmake documentation[1] I think this is a bug
in the way the build is defined:
> Do not list the output in more than one independent target that may
build in parallel or the two instances of the rule may conflict

I'll work with upstream to get this fixed. In the meantime, I'm
confident that using parallel=1 in the Debian build is the right
solution for the package.
Thanks very much for working to get this release packaged.
