Cmake error [closed]

edit

I am using Ubuntu 18.04 LTS and melodic I have entered the following commands in order:

$catkin build

but when I use the catkin build command I get a CMake error as below:

Errors     << grasp_the_dice:cmake /home/member/catkin_ws2/logs/grasp_the_dice/build.cmake.011.log

or set "rsj_pointcloud_test_DIR" to a directory containing one of the above

SDK, be sure it has been installed.
