FindOpenSceneGraph
|
|
------------------
|
|
|
|
Find OpenSceneGraph (3D graphics application programming interface)
|
|
|
|
This module searches for the OpenSceneGraph core "osg" library as well
|
|
as :module:`FindOpenThreads`, and whatever additional ``COMPONENTS``
|
|
(nodekits) that you specify.
|
|
|
|
::
|
|
|
|
See http://www.openscenegraph.org
|
|
|
|
|
|
|
|
NOTE: To use this module effectively you must either require ``CMake >=
|
|
2.6.3`` with :command:`cmake_minimum_required(VERSION 2.6.3)` or download
|
|
and place :module:`FindOpenThreads`, :module:`Findosg` functions,
|
|
:module:`Findosg` and ``Find<etc>.cmake`` files into your
|
|
:variable:`CMAKE_MODULE_PATH`.
|
|
|
|
==================================
|
|
|
|
This module accepts the following variables (note mixed case)
|
|
|
|
::
|
|
|
|
OpenSceneGraph_DEBUG - Enable debugging output
|
|
|
|
|
|
|
|
::
|
|
|
|
OpenSceneGraph_MARK_AS_ADVANCED - Mark cache variables as advanced
|
|
automatically
|
|
|
|
|
|
|
|
The following environment variables are also respected for finding the
|
|
OSG and it's various components. :variable:`CMAKE_PREFIX_PATH` can also be
|
|
used for this (see :command:`find_library` CMake documentation).
|
|
|
|
``<MODULE>_DIR``
|
|
(where ``MODULE`` is of the form "OSGVOLUME" and there is
|
|
a :module:`FindosgVolume`.cmake` file)
|
|
``OSG_DIR``
|
|
..
|
|
``OSGDIR``
|
|
..
|
|
``OSG_ROOT``
|
|
..
|
|
|
|
|
|
[CMake 2.8.10]: The CMake variable ``OSG_DIR`` can now be used as well to
|
|
influence detection, instead of needing to specify an environment
|
|
variable.
|
|
|
|
This module defines the following output variables:
|
|
|
|
::
|
|
|
|
OPENSCENEGRAPH_FOUND - Was the OSG and all of the specified components found?
|
|
|
|
|
|
|
|
::
|
|
|
|
OPENSCENEGRAPH_VERSION - The version of the OSG which was found
|
|
|
|
|
|
|
|
::
|
|
|
|
OPENSCENEGRAPH_INCLUDE_DIRS - Where to find the headers
|
|
|
|
|
|
|
|
::
|
|
|
|
OPENSCENEGRAPH_LIBRARIES - The OSG libraries
|
|
|
|
|
|
|
|
================================== Example Usage:
|
|
|
|
::
|
|
|
|
find_package(OpenSceneGraph 2.0.0 REQUIRED osgDB osgUtil)
|
|
# libOpenThreads & libosg automatically searched
|
|
include_directories(${OPENSCENEGRAPH_INCLUDE_DIRS})
|
