CMake/Modules/FindProducer.cmake

# Though Producer isn't directly part of OpenSceneGraph, its primary user
# is OSG so I consider this part of the Findosg* suite used to find 
# OpenSceneGraph components. You'll notice that I accept OSGDIR as an
# environment path.
# 
# Each component is separate and you must opt in to each module. You must 
# also opt into OpenGL (and OpenThreads?) as these 
# modules won't do it for you. This is to allow you control over your own 
# system piece by piece in case you need to opt out of certain components
# or change the Find behavior for a particular module (perhaps because the
# default FindOpenGL.cmake module doesn't work with your system as an
# example).
# If you want to use a more convenient module that includes everything,
# use the FindOpenSceneGraph.cmake instead of the Findosg*.cmake modules.
# 
# Locate Producer
# This module defines
# PRODUCER_LIBRARY
# PRODUCER_FOUND, if false, do not try to link to Producer
# PRODUCER_INCLUDE_DIR, where to find the headers
#
# $PRODUCER_DIR is an environment variable that would
# correspond to the ./configure --prefix=$PRODUCER_DIR
# used in building osg.
