I installed ros-noetic-catkin-virtualenv using the command “sudo apt install ros-noetic-catkin-virtualenv”. Then I did catkin_make, it started giving me the following error message.

CMake Error at /opt/ros/noetic/share/catkin_virtualenv/cmake/catkin_install_python.cmake:30 (message):
  range_sensor_layer loaded catkin_virtualenv, but never invoked
  'catkin_generate_virtualenv'
Call Stack (most recent call first):
  ros_lecture/externals/navigation_layers/range_sensor_layer/CMakeLists.txt:59 (catkin_install_python)

Any help or suggestion would be much appreciated!
