See https://tracker.debian.org/pkg/tracker and e.g.
http://packages.ubuntu.com/xenial-updates/amd64/libtracker-control-1.0-0/filelist .

"File list of package libtracker-control-1.0-0 in xenial-updates of
architecture amd64

/usr/lib/x86_64-linux-gnu/libtracker-control-1.0.so.0
/usr/lib/x86_64-linux-gnu/libtracker-control-1.0.so.0.602.0"

So the command should be

  ls -l /usr/{,local/}lib/{,*/}*tracker*

Something could be running, that links against libraries provided by
the "tracker" packages.
