# - Find OpenSceneGraph
# This module searches for the OpenSceneGraph core "osg" library as well as
# OpenThreads, and whatever additional COMPONENTS that you specify.
# See http://www.openscenegraph.org
#
# NOTE: If you would like to use this module in your CMAKE_MODULE_PATH instead
# of requiring CMake >= 2.6.3, you will also need to download
# FindOpenThreads.cmake, Findosg_functions.cmake, Findosg.cmake, as well as
# files for any Components you need to call (FindosgDB.cmake,
# FindosgUtil.cmake, etc.)
#
#==================================
#
# 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
#
# 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 COMPONENTS osgDB osgUtil)
# 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
