This patch adds the headers as dependencies of remote_daemon to make sure they are always in place in advance.

I'm failing to reproduce the build error, even though I put sleep(5) into both src/rpc/gendispatch.pl and src/rpc/genprotocol.pl and I try in a machine with 384 cores. I even wrapped rpcgen in a shell

In the commit message you mention libvirt-8.1.0, does this problem still occurs even with the current master?
Thanks for taking care of this. Yes, this is a rare case. We build libvirt everyday and only saw this twice so far. We haven't upgraded to a newer version. Even if it's done, we might not expect it's reproduced soon...indeed Looking at the meson.build, the dependencies are still missing on current master. Zhe
