(Very similar to this thread (Path to resource files in C++ node) but different.)

For example, OpenCV installs config files in /opt/ros/kinetic/share/OpenCV-3.1.0-dev/haarcascades on Xenial, which is under ros directory but not accessible by rospack. Hardcoding the specific path works for sure, but I'm afraid we'll need to update per every change in the upstream.

Either runtime solution in roslaunch or code C++/Python works.
