# - Try to find the Bullet physics engine
|
|
#
|
|
# This module accepts the following env variables
|
|
# BULLET_ROOT - Can be set to bullet install path or Windows build path
|
|
#
|
|
# Once done this will define
|
|
# Bullet_FOUND - System has the all required components.
|
|
# Bullet_INCLUDE_DIRS - Include directory necessary for using the required components headers.
|
|
# Bullet_LIBRARIES - Link these to use the required bullet components.
|
|
# Bullet_VERSION - Version of libbullet
|
|
#
|
|
# For each of the components
|
|
# - LinearMath
|
|
# - BulletCollision
|
|
# - BulletSoftBody
|
|
# - BulletDynamics
