# 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.

|
# 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.
