# 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. # # Created by Eric Wing. #============================================================================= # Copyright 2007-2009 Kitware, Inc. # Copyright 2012 Philip Lowman <philip@yhbt.com> # # Distributed under the OSI-approved BSD License (the "License"); # see accompanying file Copyright.txt for details. # # This software is distributed WITHOUT ANY WARRANTY; without even the # implied warranty of MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE. # See the License for more information. #============================================================================= # (To distribute this file outside of CMake, substitute the full # License text for the above reference.) # 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 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. find_path(OPENTHREADS_INCLUDE_DIR OpenThreads/Thread HINTS ENV OPENTHREADS_INCLUDE_DIR ENV OPENTHREADS_DIR ENV OSG_INCLUDE_DIR ENV OSG_DIR ENV OSGDIR ENV OpenThreads_ROOT ENV OSG_ROOT ${OPENTHREADS_DIR} ${OSG_DIR} PATHS /sw # Fink /opt/local # DarwinPorts /opt/csw # Blastwave /opt /usr/freeware PATH_SUFFIXES include ) find_library(OPENTHREADS_LIBRARY NAMES OpenThreads OpenThreadsWin32 HINTS ENV OPENTHREADS_LIBRARY_DIR ENV OPENTHREADS_DIR ENV OSG_LIBRARY_DIR ENV OSG_DIR ENV OSGDIR ENV OpenThreads_ROOT ENV OSG_ROOT ${OPENTHREADS_DIR} ${OSG_DIR} PATHS /sw /opt/local /opt/csw /opt /usr/freeware PATH_SUFFIXES lib ) find_library(OPENTHREADS_LIBRARY_DEBUG NAMES OpenThreadsd OpenThreadsWin32d HINTS ENV OPENTHREADS_DEBUG_LIBRARY_DIR ENV OPENTHREADS_LIBRARY_DIR ENV OPENTHREADS_DIR ENV OSG_LIBRARY_DIR ENV OSG_DIR ENV OSGDIR ENV OpenThreads_ROOT ENV OSG_ROOT ${OPENTHREADS_DIR} ${OSG_DIR} PATHS /sw /opt/local /opt/csw /opt /usr/freeware PATH_SUFFIXES lib ) if(OPENTHREADS_LIBRARY_DEBUG) set(OPENTHREADS_LIBRARIES optimized ${OPENTHREADS_LIBRARY} debug ${OPENTHREADS_LIBRARY_DEBUG}) else() set(OPENTHREADS_LIBRARIES ${OPENTHREADS_LIBRARY}) endif() include(${CMAKE_CURRENT_LIST_DIR}/FindPackageHandleStandardArgs.cmake) FIND_PACKAGE_HANDLE_STANDARD_ARGS(OpenThreads DEFAULT_MSG OPENTHREADS_LIBRARY OPENTHREADS_INCLUDE_DIR)
