# FindOpenSceneGraph
# ------------------
#
# Find OpenSceneGraph
#
# This module searches for the OpenSceneGraph core "osg" library as well
# as OpenThreads, 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 cmake_minimum_required(VERSION 2.6.3) or download and place
# FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, and
# Find<etc>.cmake files into your 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. CMAKE_PREFIX_PATH can also be used
# for this (see find_library() CMake documentation).
#
# ``<MODULE>_DIR``
# (where MODULE is of the form "OSGVOLUME" and there is a 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})
#
#
#
# ::
#
# add_executable(foo foo.cc)
# target_link_libraries(foo ${OPENSCENEGRAPH_LIBRARIES})
#
# Naming convention:
# Local variables of the form _osg_foo
# Input variables of the form OpenSceneGraph_FOO
# Output variables of the form OPENSCENEGRAPH_FOO
#
