Indeed, -DCMAKE_SKIP_RPATH=ON for me broke things in src:lib2geom:
https://salsa.debian.org/multimedia-team/lib2geom/-/commit/f8a4c06edbd64d4c77d69ef3aea93e978a7156e4

this is just an example, and I expect plenty of breakages.


May I recommend we do *not* enable this on the r-b builders, as I'm
positive it would break quite a few things here and there.  Rather, it
would be perfect for aws' comparative rebuilds.  Now, who is the
contact for those these days?
