1 # - Try to find Boost include dirs and libraries
2 # Usage of this module as follows:
4 # SET(Boost_USE_STATIC_LIBS ON)
5 # SET(Boost_USE_MULTITHREAD OFF)
6 # FIND_PACKAGE( Boost 1.34.1 COMPONENTS date_time filesystem iostreams ... )
8 # The Boost_ADDITIONAL_VERSIONS variable can be used to specify a list of
9 # boost version numbers that should be taken into account when searching
10 # for the libraries. Unfortunately boost puts the version number into the
11 # actual filename for the libraries, so this might be needed in the future
12 # when new Boost versions are released.
14 # Currently this module searches for the following version numbers:
15 # 1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1, 1.35, 1.35.0, 1.35.1, 1.36,
18 # The components list needs to be the actual names of boost libraries, that is
19 # the part of the actual library files that differ on different libraries. So
20 # its "date_time" for "libboost_date_time...". Anything else will result in
23 # You can provide a minimum version number that should be used. If you provide this
24 # version number and specify the REQUIRED attribute, this module will fail if it
25 # can't find the specified or a later version. If you specify a version number this is
26 # automatically put into the considered list of version numbers and thus doesn't need
27 # to be specified in the Boost_ADDITIONAL_VERSIONS variable
29 # Variables used by this module, they can change the default behaviour and need to be set
30 # before calling find_package:
31 # Boost_USE_MULTITHREAD Can be set to OFF to use the non-multithreaded
32 # boost libraries. Defaults to ON.
33 # Boost_USE_STATIC_LIBS Can be set to ON to force the use of the static
34 # boost libraries. Defaults to OFF.
35 # Boost_ADDITIONAL_VERSIONS A list of version numbers to use for searching
36 # the boost include directory. The default list
37 # of version numbers is:
38 # 1.33, 1.33.0, 1.33.1, 1.34, 1.34.0, 1.34.1,
39 # 1.35, 1.35.0, 1.35.1, 1.36, 1.36.0, 1.36.1
40 # If you want to look for an older or newer
41 # version set this variable to a list of
42 # strings, where each string contains a number, i.e.
43 # SET(Boost_ADDITIONAL_VERSIONS "0.99.0" "1.35.0")
44 # BOOST_ROOT or BOOSTROOT Preferred installation prefix for searching for Boost,
45 # set this if the module has problems finding the proper Boost installation
46 # BOOST_INCLUDEDIR Set this to the include directory of Boost, if the
47 # module has problems finding the proper Boost installation
48 # BOOST_LIBRARYDIR Set this to the lib directory of Boost, if the
49 # module has problems finding the proper Boost installation
51 # The last three variables are available also as environment variables
54 # Variables defined by this module:
56 # Boost_FOUND System has Boost, this means the include dir was found,
57 # as well as all the libraries specified in the COMPONENTS list
58 # Boost_INCLUDE_DIRS Boost include directories, not cached
59 # Boost_INCLUDE_DIR This is almost the same as above, but this one is cached and may be
60 # modified by advanced users
61 # Boost_LIBRARIES Link these to use the Boost libraries that you specified, not cached
62 # Boost_LIBRARY_DIRS The path to where the Boost library files are.
63 # Boost_VERSION The version number of the boost libraries that have been found,
64 # same as in version.hpp from Boost
65 # Boost_LIB_VERSION The version number in filename form as its appended to the library filenames
66 # Boost_MAJOR_VERSION major version number of boost
67 # Boost_MINOR_VERSION minor version number of boost
68 # Boost_SUBMINOR_VERSION subminor version number of boost
69 # Boost_LIB_DIAGNOSTIC_DEFINITIONS Only set on windows. Can be used with add_definitions
70 # to print diagnostic information about the automatic
71 # linking done on windows.
73 # For each component you list the following variables are set.
74 # ATTENTION: The component names need to be in lower case, just as the boost
75 # library names however the cmake variables use upper case for the component
76 # part. So you'd get Boost_SERIALIZATION_FOUND for example.
78 # Boost_${COMPONENT}_FOUND True IF the Boost library "component" was found.
79 # Boost_${COMPONENT}_LIBRARY The absolute path of the Boost library "component".
80 # Boost_${COMPONENT}_LIBRARY_DEBUG The absolute path of the debug version of the
81 # Boost library "component".
82 # Boost_${COMPONENT}_LIBRARY_RELEASE The absolute path of the release version of the
