FindRecastNavigation
-------
Find the RecastNavigation include directory and library.
Use this module by invoking find_package with the form::
.. code-block:: cmake
find_package(RecastNavigation
[version] # Minimum version e.g. 1.8.0
[REQUIRED] # Fail with error if RECASTNAV is not found
)
Imported targets
^^^^^^^^^^^^^^^^
This module defines the following :prop_tgt:`IMPORTED` targets:
.. variable:: RecastNavigation::Recast
Imported target for using the RECASTNAV library, if found.
Result variables
^^^^^^^^^^^^^^^^
.. variable:: RECASTNAV_FOUND
Set to true if RECASTNAV library found, otherwise false or undefined.
.. variable:: RECASTNAV_INCLUDE_DIRS
Paths to include directories listed in one variable for use by RECASTNAV client.
.. variable:: RECASTNAV_LIBRARIES
Paths to libraries to linked against to use RECASTNAV.
.. variable:: RECAST_VERSION
The version string of RECASTNAV found.
Cache variables
^^^^^^^^^^^^^^^
For users who wish to edit and control the module behavior, this module
reads hints about search locations from the following variables::
.. variable:: RECASTNAV_INCLUDE_DIR
Path to RECASTNAV include directory with ``Recast.h`` header.
.. variable:: RECASTNAV_LIBRARY
Path to RECASTNAV library to be linked.
NOTE: The variables above should not usually be used in CMakeLists.txt files!
