I am trying to use libiio that is in the 3rdParty folder,

everything seems to compile and install fine but can’t debug ?

sshWrapper: /legato/systems/current/apps/hubApp/read-only/bin/MCExe: error while loading shared libraries: libiio.so.0: cannot open shared object file: No such file or directory

the library is on the device (i tried to put it in different locations)
