I want to connect to files stored at CERN from my personal laptop. To that end, I’ve been trying to follow these outdated-looking instructions to setup xrootd to work with my root installation to no avail. If I do root-config --has-xrootd, I get no back. If I follow the instructions linked above, th…

Adding the cmake flag -Dbuiltin_xrootd=On should do! I.e. for an existing build you could do cmake -Dbuiltin_xrootd=On .
