CMake error with custom messages

edit

I created 2 custom messages in my package to publish data through one of my nodes. The .msg files are:

bearing_angles.msg

float left_edge
float right edge

bearArray.msg

bearArray[] bear_array

I changes my CMakeLists.txt of my package, so it looks like this:

find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
  message_generation
)

add_message_files(
  FILES
  Num.msg
  bearing_angles.msg
  bearArray.msg
)

generate_messages(
  DEPENDENCIES
  std_msgs
)

catkin_package(
#  INCLUDE_DIRS include
#  LIBRARIES door_detector_1
  CATKIN_DEPENDS roscpp rospy std_msgs message_runtime
#  DEPENDS system_lib
)

But when I build my package from catkin_ws directory, with catkin_make, I get this error:

I think I miss something in the CMakeLists.txt file, but I didn't find it so far. What am I missing here? Any feedback is appreciated.

I use Ubuntu 18, ROS melodic, and my node is written in python 2.7

UPDATE (CMake error): After @gvdhoorn answer
