Catkin can't install this package correctly because there are no Install statements in the CMakeLists.txt.

hello,
My setup is Kinetic on ubuntu xenial (arm) so as you can imagine it was a bit of a pain to set this up but i managed to get classify to work. but I get the following exception when i try to print from
detection's /detections :

Traceback (most recent call last):

any idea what might be wrong ?
