Meson has support for using install_name_tool to remove "build time" rpaths and set "install time" rpaths during the installation process - which uses install_name_tool on mac. If, and perhaps that's too big an if, relative rpaths actually work despite SIP, it might be worth setting a relative install_rpath, because afaict that should then work both for a "real" installation and our temporary test one. If absolute rpaths are required, it'd make the process a bit more expensive, because we'd probably need to change a configure time option during the temporary install. No actual rebuilds would be required, but still. Greetings, Andres Freund
