PCL version Requirements

[LongruiDong]

Hi~
Thanks for sharing your great codes~
when I run catkin_make, I met this Error:

-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-- ~~  traversing 1 packages in topological order:
-- ~~  - loam_velodyne_kitti_ros
-- ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-- +++ processing catkin package: 'loam_velodyne_kitti_ros'
-- ==> add_subdirectory(loam_velodyne_kitti_ros)
-- Using these message generators: gencpp;geneus;genlisp;gennodejs;genpy
CMake Error at loam_velodyne_kitti_ros/CMakeLists.txt:17 (find_package):
  Could not find a configuration file for package "PCL" that is compatible
  with requested version "1.8".

  The following configuration files were considered but not accepted:

    /usr/lib/x86_64-linux-gnu/cmake/pcl/PCLConfig.cmake, version: 1.7.2

my enironments:

Ubuntu 16.04 
ros kinetic

So do I have to change PCL to 1.8？ Will it be compatible with lower versions of PCL by other methods?

I think that it would also work with lower versions of PCL, just change it in the CMakeLists.txt file.
