Unable to complete cmake of openni2_camera

edit

Hi, I'm new to these software and programs, pardon me if the question are too naive. I'm using Odroid XU3(Arm processor), Ubuntu 12.04(Precise) and ROS(Hydro). When I run catkin_make on openni2_camera, I get these error

-- +++ processing catkin package: 'openni2_camera'
-- ==> add_subdirectory(openni2_camera)
CMake Error at openni2_camera/CMakeLists.txt:11 (pkg_check_modules):
  Unknown CMake command "pkg_check_modules".

-- Configuring incomplete, errors occurred!
Invoking "cmake" failed

Is there any method to solve this?
