#.rst: # FindBoost # --------- # # Find Boost include dirs and libraries # # Use this module by invoking find_package with the form:: # # find_package(Boost # [version] [EXACT] # Minimum or EXACT version e.g. 1.36.0 # [REQUIRED] # Fail with error if Boost is not found # [COMPONENTS <libs>...] # Boost libraries by their canonical name # ) # e.g. "date_time" for "libboost_date_time" # # This module finds headers and requested component libraries OR a CMake # package configuration file provided by a "Boost CMake" build. For the # latter case skip to the "Boost CMake" section below. For the former # case results are reported in variables:: # # Boost_FOUND - True if headers and requested libraries were found # Boost_INCLUDE_DIRS - Boost include directories # Boost_LIBRARY_DIRS - Link directories for Boost libraries # Boost_LIBRARIES - Boost component libraries to be linked # Boost_<C>_FOUND - True if component <C> was found (<C> is upper-case) # Boost_<C>_LIBRARY - Libraries to link for component <C> (may include # target_link_libraries debug/optimized keywords) # Boost_VERSION - BOOST_VERSION value from boost/version.hpp # Boost_LIB_VERSION - Version string appended to library filenames # Boost_MAJOR_VERSION - Boost major version number (X in X.y.z) # Boost_MINOR_VERSION - Boost minor version number (Y in x.Y.z) # Boost_SUBMINOR_VERSION - Boost subminor version number (Z in x.y.Z) # Boost_LIB_DIAGNOSTIC_DEFINITIONS (Windows) # - Pass to add_definitions() to have diagnostic # information about Boost's automatic linking # displayed during compilation # # This module reads hints about search locations from variables:: # # BOOST_ROOT - Preferred installation prefix # (or BOOSTROOT) # BOOST_INCLUDEDIR - Preferred include directory e.g. <prefix>/include # BOOST_LIBRARYDIR - Preferred library directory e.g. <prefix>/lib # Boost_NO_SYSTEM_PATHS - Set to ON to disable searching in locations not # specified by these hint variables. Default is OFF. # Boost_ADDITIONAL_VERSIONS # - List of Boost versions not known to this module # (Boost install locations may contain the version) # # and saves search results persistently in CMake cache entries:: # # Boost_INCLUDE_DIR - Directory containing Boost headers # Boost_LIBRARY_DIR - Directory containing Boost libraries # Boost_<C>_LIBRARY_DEBUG - Component <C> library debug variant # Boost_<C>_LIBRARY_RELEASE - Component <C> library release variant # # Users may set these hints or results as cache entries. Projects # should not read these entries directly but instead use the above # result variables. Note that some hint names start in upper-case # "BOOST". One may specify these as environment variables if they are # not specified as CMake variables or cache entries. # # This module first searches for the Boost header files using the above # hint variables (excluding BOOST_LIBRARYDIR) and saves the result in # Boost_INCLUDE_DIR. Then it searches for requested component libraries # using the above hints (excluding BOOST_INCLUDEDIR and # Boost_ADDITIONAL_VERSIONS), "lib" directories near Boost_INCLUDE_DIR, # and the library name configuration settings below. It saves the # library directory in Boost_LIBRARY_DIR and individual library # locations in Boost_<C>_LIBRARY_DEBUG and Boost_<C>_LIBRARY_RELEASE. # When one changes settings used by previous searches in the same build # tree (excluding environment variables) this module discards previous # search results affected by the changes and searches again. # # Boost libraries come in many variants encoded in their file name. # Users or projects may tell this module which variant to find by # setting variables:: # # Boost_USE_MULTITHREADED - Set to OFF to use the non-multithreaded # libraries ('mt' tag). Default is ON. # Boost_USE_STATIC_LIBS - Set to ON to force the use of the static # libraries. Default is OFF. # Boost_USE_STATIC_RUNTIME - Set to ON or OFF to specify whether to use # libraries linked statically to the C++ runtime # ('s' tag). Default is platform dependent. # Boost_USE_DEBUG_RUNTIME - Set to ON or OFF to specify whether to use # libraries linked to the MS debug C++ runtime # ('g' tag). Default is ON. # Boost_USE_DEBUG_PYTHON - Set to ON to use libraries compiled with a # debug Python build ('y' tag). Default is OFF. # Boost_USE_STLPORT - Set to ON to use libraries compiled with # STLPort ('p' tag). Default is OFF. # Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS # - Set to ON to use libraries compiled with # STLPort deprecated "native iostreams" # ('n' tag). Default is OFF. # Boost_COMPILER - Set to the compiler-specific library suffix # (e.g. "-gcc43"). Default is auto-computed # for the C++ compiler in use. # Boost_THREADAPI - Suffix for "thread" component library name, # such as "pthread" or "win32". Names with # and without this suffix will both be tried. # Boost_NAMESPACE - Alternate namespace used to build boost with # e.g. if set to "myboost", will search for # myboost_thread instead of boost_thread. # # Other variables one may set to control this module are:: # # Boost_DEBUG - Set to ON to enable debug output from FindBoost. # Please enable this before filing any bug report. # Boost_DETAILED_FAILURE_MSG # - Set to ON to add detailed information to the # failure message even when the REQUIRED option # is not given to the find_package call. # Boost_REALPATH - Set to ON to resolve symlinks for discovered # libraries to assist with packaging. For example, # the "system" component library may be resolved to # "/usr/lib/libboost_system.so.1.42.0" instead of # "/usr/lib/libboost_system.so". This does not # affect linking and should not be enabled unless # the user needs this information. # # On Visual Studio and Borland compilers Boost headers request automatic # linking to corresponding libraries. This requires matching libraries # to be linked explicitly or available in the link library search path. # In this case setting Boost_USE_STATIC_LIBS to OFF may not achieve # dynamic linking. Boost automatic linking typically requests static # libraries with a few exceptions (such as Boost.Python). Use:: # # add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS}) # # to ask Boost to report information about automatic linking requests. # # Example to find Boost headers only:: # # find_package(Boost 1.36.0) # if(Boost_FOUND) # include_directories(${Boost_INCLUDE_DIRS}) # add_executable(foo foo.cc) # endif() # # Example to find Boost headers and some *static* libraries:: # # set(Boost_USE_STATIC_LIBS ON) # only find static libs # set(Boost_USE_MULTITHREADED ON) # set(Boost_USE_STATIC_RUNTIME OFF) # find_package(Boost 1.36.0 COMPONENTS date_time filesystem system ...) # if(Boost_FOUND) # include_directories(${Boost_INCLUDE_DIRS}) # add_executable(foo foo.cc) # target_link_libraries(foo ${Boost_LIBRARIES}) # endif() # # Boost CMake # ^^^^^^^^^^^ # # If Boost was built using the boost-cmake project it provides a package # configuration file for use with find_package's Config mode. This # module looks for the package configuration file called # BoostConfig.cmake or boost-config.cmake and stores the result in cache # entry "Boost_DIR". If found, the package configuration file is loaded # and this module returns with no further action. See documentation of # the Boost CMake package configuration for details on what it provides. # # Set Boost_NO_BOOST_CMAKE to ON to disable the search for boost-cmake. #============================================================================= # Copyright 2006-2012 Kitware, Inc. # Copyright 2006-2008 Andreas Schneider <mail@cynapses.org> # Copyright 2007 Wengo # Copyright 2007 Mike Jackson # Copyright 2008 Andreas Pakulat <apaku@gmx.de> # Copyright 2008-2012 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.) #------------------------------------------------------------------------------- # Before we go searching, check whether boost-cmake is available, unless the # user specifically asked NOT to search for boost-cmake. # # If Boost_DIR is set, this behaves as any find_package call would.
