Hi Alex,

The PATH seems wrong. After sourcing setup.bash in catkin_ws/devel (see ros instructions), the PATH should look more like this (on my system):

$ env | grep PATH
PATH=/home/mathieu/catkin_ws/devel/bin:/opt/ros/kinetic/bin...

The "catkin_ws/devel/bin" is before "/opt/ros/kinetic/bin", which is used by cmake to find the libraries built in your catkin workspace.

Maybe the isolated build doesn't create "catkin_ws/devel/bin". I don't use isolated builds so I am not sure how libraries can be linked from outside the workspace.

Another option is to set the path of libfovis and loam_velodyne config files:

$ cd rtabmap/build
$ cmake -Dloam_velodyne_DIR=~/catkin_ws/devel/share/loam_velodyne/cmake -Dlibfovis_DIR=~/catkin_ws/devel/share/libfovis/cmake

cheers,
Mathieu
