# FindBullet

Finds the Bullet physics engine:

    find_package(Bullet [...])

## Result Variables

This module defines the following variables:

`Bullet_FOUND`

  Added in version 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 since version 4.2: Use `Bullet_FOUND`, which has the same value.

  Boolean indicating whether Bullet was found.

## Examples

Finding Bullet and conditionally creating an interface imported target that encapsulates its usage requirements for linking to a project target:

    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()

    target_link_libraries(example PRIVATE Bullet::Bullet)
