Hello! I am using voxl-cross version 4.4 and I am getting this error:
```
make[2]: *** No rule to make target '/usr/lib64/libceres.so', needed by 'server/mav_path_smoothing/libmav_path_smoothing.so'.  Stop.
make[1]: *** [CMakeFiles/Makefile2:385: server/mav_path_smoothing/CMakeFiles/mav_path_smoothing.dir/all] Error 2
make[1]: *** Waiting for unfinished jobs....
[ 44%] Built target voxblox_planning_common
make: *** [Makefile:136: all] Error 2
```
 I have also tried building with 4.0 and nothing works. How can I fix this?
I tried installing it with: apt install -y libceres-dev libeigen3-dev libgoogle-glog-dev libgflags-dev
 and it didn't work.
It's for a Starling2. (VOXL2)
