I'm not the Debian maintainer for highway, but here's a suggestion: -Depends: @, g++ +Depends: libhwy-dev, g++
since the point of this is to test that libhwy-dev works and has its Depends set correctly. I have uploaded your patch with my suggested change to Ubuntu since we need an autopkgtest like this there for Ubuntu main inclusion processes. https://launchpad.net/ubuntu/+source/highway/1.2.0-3ubuntu1 Thank you, Jeremy Bícha
