to avoid mold you need to:
 - uninstall mold or move it out out $PATH
 - explicitly pass -DUSE_MOLD_LINKER=OFF
 - explicitly pass -DCMAKE_LINKER_TYPE=LLD (or another cmake supported linker)

some linux distros allow you to set the default linker using `alternatives`.
maybe developers can try `alternatives --config ld` instead?
otherwise pass -DCMAKE_LINKER_TYPE=MOLD

also maybe we should ask the sysadmins to have the CI set CMAKE_LINKER_TYPE=MOLD for us

I've been setting CMAKE_LINKER_TYPE=LLD for a long time since I use clang++ to compile
but maybe I will try mold.
