-- NLopt found (include: NLOPT_INCLUDE_DIR-NOTFOUND, link: /opt/ros/kinetic/lib/libnlopt_cxx.so)
CMake Error: The following variables are used in this project, but they are set to NOTFOUND.
Please set them or make sure they are set and tested correctly in the CMake files:
NLOPT_INCLUDE_DIR (ADVANCED)
This appears to be a regression recently in being able to find nlopt via CMAKE.
