#.rst:
# FindOpenThreads
# ---------------
#
#
#
# OpenThreads is a C++ based threading library.  Its largest userbase
# seems to OpenSceneGraph so you might notice I accept OSGDIR as an
# environment path.  I consider this part of the Findosg* suite used to
# find OpenSceneGraph components.  Each component is separate and you
# must opt in to each module.
#
# Locate OpenThreads This module defines OPENTHREADS_LIBRARY
# OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
# OPENTHREADS_INCLUDE_DIR, where to find the headers
#
# $OPENTHREADS_DIR is an environment variable that would correspond to
# the ./configure --prefix=$OPENTHREADS_DIR used in building osg.
#
# [CMake 2.8.10]: The CMake variables OPENTHREADS_DIR or OSG_DIR can now
# be used as well to influence detection, instead of needing to specify
# an environment variable.
#

# Header files are presumed to be included like
# #include <OpenThreads/Thread>

# To make it easier for one-step automated configuration/builds,
# we leverage environmental paths. This is preferable
# to the -DVAR=value switches because it insulates the
# users from changes we may make in this script.
# It also offers a little more flexibility than setting
# the CMAKE_*_PATH since we can target specific components.
# However, the default CMake behavior will search system paths
# before anything else. This is problematic in the cases
# where you have an older (stable) version installed, but
# are trying to build a newer version.
# CMake doesn't offer a nice way to globally control this behavior
# so we have to do a nasty "double FIND_" in this module.
# The first FIND disables the CMAKE_ search paths and only checks
# the environmental paths.
# If nothing is found, then the second find will search the
# standard install paths.
# Explicit -DVAR=value arguments should still be able to override everything.
