Alex Neundorf b01184022b Use absolute path to FindPackageHandleStandardArgs.cmake everywhere
This is to avoid getting an (older) copy of FPHSA.cmake which is
e.g. installed with KDE 4.5.0 and 4.5.1.

# 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.

# 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.
