+# - 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
