Compiling Sphero ROS on Melodic: gzmath.h no such file or directory

edit

I have ROS Melodic on my computer. I started by installing Sphero ROS ( https://github.com/eborghi10/Sphero-ROS ) for controlling through the keyboard. Then I also installed ROS turtlebot ( https://github.com/turtlebot/turtlebot ). Finally I installed the Robot Controllers ( https://github.com/fetchrobotics/robo... ). I ran catkin_make but I keep getting this error -

/home/ritesh/catkin_ws/src/Sphero-ROS-master/sphero_gazebo/src/gazebo_sphero_controller.cpp:23:10: fatal error: gazebo/math/gzmath.hh: No such file or directory

I looked for solutions online but am unable to fix it. Can someone help please?
