hi i try to move my Husky A200 a little bit smoother. Therefor i've installed the yocsvelocitysmoother. But it doesn't start. Nodelet failed to load. I saw that others have nearly the same problems and they only must add a new library through the "CMakeLists.txt" file. But i don't know which library i had to add. My error look like this:

Failed to load nodelet [/velocitysmoother] of type [yocsvelocitysmoother/VelocitySmootherNodelet]: Could not find library corresponding to plugin yocsvelocitysmoother/VelocitySmootherNodelet. Make sure the plugin description XML file has the correct name of the library and that the library actually exists. Service call failed! Service call failed! [velocitysmoother-3] process has died [pid 2531, exit code 255, cmd /opt/ros/groovy/lib/nodelet/nodelet load yocsvelocitysmoother/VelocitySmootherNodelet nodeletmanager velocitysmoother/odometry:=odom velocitysmoother/rawcmdvel:=cmdvel/input velocitysmoother/smoothcmdvel:=cmdvel/output _name:=velocitysmoother _log:=/home/at-labor/.ros/log/02c136b8-da48-11e2-9d90-50e549813a28/velocitysmoother-3.log]. log file: /home/at-labor/.ros/log/02c136b8-da48-11e2-9d90-50e549813a28/velocity_smoother-3*.log
