# FindProducer

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` 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` 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:

    ./configure --prefix=$PRODUCER_DIR

used in building osg.
