no such file: ugv_sdk/mobile_robot/ranger_robot.hpp

I got tow problem building the project.
First,when I run "cd ranger_ros/ranger_base/ascent" ,there comes a error:there is no such file.And I found that ascent is at the dir src/ranger_ros/ranger_base/include.And there is no way to build and install.
And I skip that step.
Second,I run"catkin_make install".Here comes the error: src/ranger_ros/ranger_base/include/ranger_base/ranger_messenger.hpp:24:10: fatal error: ugv_sdk/mobile_robot/ranger_robot.hpp: no such file
How should I do? Thank u.
