Modules/FindOpenThreads.cmake

   1 # OpenThreads is a C++ based threading library. Its largest userbase
   2 # seems to OpenSceneGraph so you might notice I accept OSGDIR as an
   3 # environment path.
   4 # I consider this part of the Findosg* suite used to find OpenSceneGraph
   5 # components.
   6 # Each component is separate and you must opt in to each module.

   8 # Locate OpenThreads
   9 # This module defines
  10 # OPENTHREADS_LIBRARY
  11 # OPENTHREADS_FOUND, if false, do not try to link to OpenThreads
  12 # OPENTHREADS_INCLUDE_DIR, where to find the headers
  13 #
  14 # $OPENTHREADS_DIR is an environment variable that would
  15 # correspond to the ./configure --prefix=$OPENTHREADS_DIR
  16 # used in building osg.

  20 # Header files are presumed to be included like
  21 # #include <OpenThreads/Thread>
  22
  23 # To make it easier for one-step automated configuration/builds,
  24 # we leverage environmental paths. This is preferable
  25 # to the -DVAR=value switches because it insulates the
  26 # users from changes we may make in this script.
  27 # It also offers a little more flexibility than setting
  28 # the CMAKE_*_PATH since we can target specific components.
  29 # However, the default CMake behavior will search system paths
  30 # before anything else. This is problematic in the cases
  31 # where you have an older (stable) version installed, but
  32 # are trying to build a newer version.
  33 # CMake doesn't offer a nice way to globally control this behavior
  34 # so we have to do a nasty "double FIND_" in this module.
  35 # The first FIND disables the CMAKE_ search paths and only checks
  36 # the environmental paths.
  37 # If nothing is found, then the second find will search the
  38 # standard install paths.
  39 # Explicit -DVAR=value arguments should still be able to override everything.
