~/catkin_ws/src/LMS1xx$ rosrun lms1xx find_sick but
No lasers found.

linux@linux-MXE5400:/catkin_ws/src/LMS1xx/build$ source devel/setup.bash
linux@linux-MXE5400:/catkin_ws/src/LMS1xx/build$ rosrun lms1xx LMS1xx_node

[rosrun] Couldn't find executable named LMS1xx_node below /home/linux/catkin_ws/src/LMS1xx

[rosrun] Found the following, but they're either not files,
[rosrun] or not executable:
[rosrun] /home/linux/catkin_ws/src/LMS1xx/build/devel/lib/lms1xx/LMS1xx_node
