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

[1]: https://cmake.org/cmake/help/latest/command/add_custom_command.html

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.
