face_detector 1.1.2 failed to build on melodic

[ustyui]

face_detector gives following errors when catkin_make on nvidia Xavier.

make[2]: *** No rule to make target '/usr/lib/aarch64-linux-gnu/libopencv_photo.so.3.2.0', needed by '/home/nvidia/catkin_ws/devel/lib/face_detector/face_detector'.  Stop.

make[1]: *** [people/face_detector/CMakeFiles/face_detector.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
[ 84%] Built target face_detector_generate_messages

Anyone knows the reason? Thank you in advance.

Do you have all the dependencies installed?

[ustyui]

Yes, I used
rosdep install --from-paths src -i -r -n -y
to install dependencies but error still occurs.
I do this on NVIDIA AGX Xavier.

Using a jetson nano, 18.04 and getting the errors show below when compiling face_detector:
