# - Find OPENDE
# This module finds if Open Dynamics Engine (OPENDE) is
# installed and determines where the include files and libraries
# are. The OPENDE_PATH variable (or environment variable) can be set
# to specify where to look for OPENDE. In addition, OPENDE_LIB_PATH
# and OPENDE_INCLUDE_PATH can be set to specify locations for the ode
# library and include files as well.
#
# The following variables are set:
# OPENDE_LIBRARY = location of OPENDE library
# OPENDE_INCLUDE_DIR = include path for OPENDE
# OPENDE_DEFINITIONS = defines for OPENDE; such as -DdSINGLE
# OPENDE_VERSION = the version of OPENDE that was found; empty if ode-config was not found
