ERROR: cannot launch node of type [netft_rdt_driver/netft_node]: netft_rdt_driver

[hansen95]

Forgive me if I am misusing or misunderstanding... still a ROS novice.

I cloned the netft_utils repository and built for Melodic with "catkin build".
I was able to
rosrun netft_utils netft_node my_ip_address rosrun netft_utils netft_utils base_frame my_ft_sensor_frame
according to instructions on ROS Wiki.
But when I tried
roslaunch netft_utils netft_view.launch
I would get ERROR: cannot launch node of type [netft_rdt_driver/netft_node]: netft_rdt_driver

The launch file I cloned includes this line:
<node name="netft_node" pkg="netft_rdt_driver" type="netft_node" respawn="false" output="screen" args="192.168.1.84"/>

I changed to:
<node name="netft_node" pkg="netft_utils" type="netft_node" respawn="false" output="screen" args="my_ip_address"/>
and launch file works as expected with no error.
