catkin_make does not work since I modified CMakeLists.txt file

edit

I have started using ROS a few days ago and I am following the official tutorials(http://wiki.ros.org/ROS/Tut.... Now I need create a msg an srv. I followed the steps in the "2.1 Creating a msg" part and modified my CMakeList.txt file. It now looks like this (I am putting just the uncommented parts since the editor detecs the lines which start with "#" as a bold text:

    find_package(catkin REQUIRED COMPONENTS
  roscpp
  rospy
  std_msgs
  message_generation
)

 catkin_package(
        CATKIN_DEPENDS message_runtime
    )

 add_message_files(
   FILES
   Num.msg
 )

 generate_messages(
   DEPENDENCIES
   std_msgs
 )

After these configurations, on a new terminal I tried to run catkin_make on my workspace folder and I received an error such as:

C:\Windows\System32>cd C:\opt\ros\noetic\x64\ros_workspace
