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

||||
|
||||
.. variable:: RECASTNAV_INCLUDE_DIR
|
||||
|
||||
Path to RECASTNAV include directory with ``Recast.h`` header.
|
||||
|
||||
.. variable:: RECASTNAV_LIBRARY
|
