title: ROS Multiple Packages
body: <p>I want to create multiple packages inside a single catkin workspace. I created my package <code>my_first_pkg</code> inside <code>catkin_ws/src</code>. It worked fine.</p>
  
  <p>Then I tried to add another package in the same path <code>catkin_ws/src</code> with the name <code>my_second_pkg</code> using <code>catkin_create_pkg</code>. Then I run <code>catkin_make</code>.</p>
  
  <p>It gives me the following error:</p>
  
  <blockquote>
    <p>Invoking "make cmake_check_build_system" failed.</p>
  </blockquote>
  
  <p>Can you please tell me how to solve this error?</p>
