FindBullet
----------
Finds the Bullet physics engine:
.. code-block:: cmake
find_package(Bullet [...])
Result Variables
^^^^^^^^^^^^^^^^
This module defines the following variables:
``Bullet_FOUND``
.. versionadded:: 3.3
Boolean indicating whether Bullet was found.
``BULLET_INCLUDE_DIRS``
The Bullet include directories.
``BULLET_LIBRARIES``
Libraries needed to link to Bullet. By default, all Bullet components
(Dynamics, Collision, LinearMath, and SoftBody) are added.
Hints
^^^^^
This module accepts the following variables:
``BULLET_ROOT``
Can be set to Bullet install path or Windows build path to specify where to
find Bullet.
Deprecated Variables
^^^^^^^^^^^^^^^^^^^^
The following variables are provided for backward compatibility:
``BULLET_FOUND``
.. deprecated:: 4.2
Use ``Bullet_FOUND``, which has the same value.
Boolean indicating whether Bullet was found.
Examples
^^^^^^^^
Finding Bullet and conditionally creating an interface :ref:`imported target
<Imported Targets>` that encapsulates its usage requirements for linking to a
project target:
.. code-block:: cmake
find_package(Bullet)
if(Bullet_FOUND AND NOT TARGET Bullet::Bullet)
add_library(Bullet::Bullet INTERFACE IMPORTED)
set_target_properties(
Bullet::Bullet
PROPERTIES
INTERFACE_INCLUDE_DIRECTORIES "${BULLET_INCLUDE_DIRS}"
INTERFACE_LINK_LIBRARIES "${BULLET_LIBRARIES}"
)
endif()
