   1 # - Try to find Boost include dirs and libraries
   2 # Usage of this module as follows:
   3 #
   4 #     FIND_PACKAGE( Boost COMPONENTS date_time filesystem iostreams ... )
   5 #
   6 # The Boost_ADDITIONAL_VERSIONS variable can be used to specify a list of
   7 # boost version numbers that should be taken into account when searching
   8 # for the libraries. Unfortunately boost puts the version number into the
   9 # actual filename for the libraries, so this might be needed in the future
  10 # when new boost versions are released.
  11 #
  12 # Currently this module searches for the following version numbers:
  13 # 1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1
  14 #
  15 # The components list needs to be the actual names of boost libraries, that is
  16 # the part of the actual library files that differ on different libraries. So
  17 # its "date_time" for "libboost_date_time...". Anything else will result in
  18 # errors
  19 #
  20 # Variables used by this module, they can change the default behaviour:
  21 #  Boost_USE_NONMULTITHREAD      Can be set to TRUE to use the non-multithreaded
  22 #                                boost libraries.
  23 #  Boost_ADDITIONAL_VERSIONS     A list of version numbers to use for searching
  24 #                                the boost include directory. The default list
  25 #                                of version numbers is:
  26 #                                1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1
  27 #                                If you want to look for an older or newer
  28 #                                version set this variable to a list of
  29 #                                strings, where each string contains a number, i.e.
  30 #                                SET(Boost_ADDITIONAL_VERSIONS "0.99.0" "1.35.0")
  31 #  Boost_ROOT                    Preferred installation prefix for searching for Boost,
  32 #                                set this if the module has problems finding the proper Boost installation
  33 #  Boost_INCLUDEDIR              Set this to the include directory of Boost, if the
  34 #                                module has problems finding the proper Boost installation
  35 #  Boost_LIBRARYDIR              Set this to the lib directory of Boost, if the
  36 #                                module has problems finding the proper Boost installation
  37 #
  38 #  The last three variables are available also as environment variables
  39 #
  40 #
  41 # Variables defined by this module:
  42 #
  43 #  Boost_FOUND                System has Boost, this means the include dir was found,
  44 #                             as well as all the libraries specified in the COMPONENTS list
  45 #  Boost_INCLUDE_DIRS         Boost include directories, not cached
  46 #  Boost_INCLUDE_DIR          This is almost the same as above, but this one is cached and may be
  47 #                             modified by advanced users
  48 #  Boost_LIBRARIES            Link these to use the Boost libraries that you specified, not cached
  49 #  Boost_LIBRARY_DIRS         The path to where the Boost library files are.
  50 #  Boost_VERSION              The version number of the boost libraries that have been found,
  51 #                             same as in version.hpp from Boost
  52 #  Boost_LIB_VERSION          The version number in filename form as its appended to the library filenames
  53 #  Boost_MAJOR_VERSION        major version number of boost
  54 #  Boost_MINOR_VERSION        minor version number of boost
  55 #  Boost_SUBMINOR_VERSION     subminor version number of boost
  56
  57 # For each component you list the following variables are set.
  58 # ATTENTION: The component names need to be in lower case, just as the boost
  59 # library names however the cmake variables use upper case for the component
  60 # part. So you'd get Boost_SERIALIZATION_FOUND for example.
  61 #
  62 #  Boost_${COMPONENT}_FOUND             True IF the Boost library "component" was found.
  63 #  Boost_${COMPONENT}_LIBRARY           The absolute path of the Boost library "component".
  64 #  Boost_${COMPONENT}_LIBRARY_DEBUG     The absolute path of the debug version of the
  65 #                                       Boost library "component".
  66 #  Boost_${COMPONENT}_LIBRARY_RELEASE   The absolute path of the release version of the
  67 #                                       Boost library "component"
