Invoking "cmake" failed

edit

I have previously installed Ubuntu 16.04 LTS and ROS kinetic on PC. I try to practice tutorial according this ( http://wiki.ros.org/cv_bridge/Tutoria... )

I create a package using catkin_create_pkg sample_opencv_pkg sensor_msgs opencv2 cv_bridge rospy std_msgs. the terminal shows

Created file sample_opencv_pkg/CMakeLists.txt
Created file sample_opencv_pkg/package.xml
Created folder sample_opencv_pkg/src
Successfully created files in /home/my/catkin_ws/src/sample_opencv_pkg. Please adjust the values in package.xml.

Then I change direction to catkin_ws ,and use catkin_make .The terminal show the following error:
