----------

Try to find the Bullet physics engine

This module defines the following variables

BULLET_FOUND - Was bullet found
  BULLET_INCLUDE_DIRS - the Bullet include directories
  BULLET_LIBRARIES - Link to this, by default it includes
                     all bullet components (Dynamics,
                     Collision, LinearMath, & SoftBody)

This module accepts the following variables

BULLET_ROOT - Can be set to bullet install path or Windows build path
