Find Coin3D (Open Inventor)

Coin3D is an implementation of the Open Inventor API.  It provides
data structures and algorithms for 3D visualization.

This module defines the following variables

::

  COIN3D_FOUND         - system has Coin3D - Open Inventor
  COIN3D_INCLUDE_DIRS  - where the Inventor include directory can be found
  COIN3D_LIBRARIES     - Link to this to use Coin3D
