How to install perception_oru package from github?

edit

I have tried to install perception_oru package from github. But I had faced problem while approaching the following steps:

$ git clone https://github.com/tstoyanov/perception_oru-release.git
$ cd perception_oru-release
$ mkdir build
$ cd build
$ cmake ..

Then the following error appears.

CMake Error: The source directory "/home/baban/perception_oru-release" does not appear to contain CMakeLists.txt.

I need to know if there is any cmakelists.txt for this package or how to install this package. This is the prerequisite to create NDT map using NDTfuser.

thank you
