I am not sure what the issues is but could you post the CMake errors?

first thing i really appreciate the fast answer from you and really sorry not being able to rewrite was really out of my hand and my ability
first thing that i noted that when i do catkin build it really takes too much time (around 4 mins ) i dont know if that is normal or abnormal
there is alot of warnings that appears like that one :
