Running catkin_make -DCMAKE_BUILD_TYPE="Release" produces error

[yohannes-taye]

Im using a virtual machine running Ubuntu 18.04 and ROS melodic. I have been trying to figure out this error for the past week but have failed to figure it out. I am trying to connect a kinect v2 to ROS and after I have cloned the code, running catkin_make -DCMAKE_BUILD_TYPE="Release" produces the following error.
