how to install bullet on Indigo in Ubuntu

edit

I have been trying to build this project, it has tf2_bullet which is part of geometry_experimental in it and depends on bullet, So I have been getting this error message whenever I try to do catkin_make

 add_subdirectory(geometry_experimental/tf2_bullet)
-- checking for module 'bullet'
--   package 'bullet' not found

I have done some research and I could not find bullet package. I installed bullet3 from bullet github but that did not solve the problem Any help would be appreciated...
