FindPhysFS
----------

Finds the PhysicsFS library (PhysFS) for file I/O abstraction:

.. code-block:: cmake

  find_package(PhysFS [...])

Result Variables
^^^^^^^^^^^^^^^^

This module defines the following variables:

``PhysFS_FOUND``
  Boolean indicating whether PhysicsFS library is found.  For backward
  compatibility, the ``PHYSFS_FOUND`` variable is also set to the same value.

Cache Variables
^^^^^^^^^^^^^^^

The following cache variables may also be set:

``PHYSFS_INCLUDE_DIR``
  Directory containing the ``<physfs.h>`` and related headers needed for using
  the library.
``PHYSFS_LIBRARY``
  Path to the PhysicsFS library needed to link against.

Hints
^^^^^

This module accepts the following variables:

``PHYSFSDIR``
  Environment variable that can be set to help locate a PhysicsFS library
  installed in a custom location.  It should point to the installation
  destination that was used when configuring, building, and installing PhysicsFS
  library: ``./configure --prefix=$PHYSFSDIR``.
