AUTOBUILD: Please build all targets

There's a warning in the CI. Not sure if it's relevant. Probably build with all targets here gave this error. --> try without in another PR

I think it needs a CodeQL run against the target branch -- master -- for both configurations. So I guess we need this merged and run at least twice on master before we can check any other branches and not get warnings. (One other merge, with build_all_targets:false after this one, that is.)
