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_MACRO - BOOST_VERSION value from boost/version.hpp + Boost_VERSION_STRING - Boost version number in x.y.z format + Boost_VERSION - if CMP0093 NEW => same as Boost_VERSION_STRING + if CMP0093 OLD or unset => same as Boost_VERSION_MACRO + Boost_LIB_VERSION - Version string appended to library filenames + Boost_VERSION_MAJOR - Boost major version number (X in X.y.z) + alias: Boost_MAJOR_VERSION + Boost_VERSION_MINOR - Boost minor version number (Y in x.Y.z) + alias: Boost_MINOR_VERSION + Boost_VERSION_PATCH - Boost subminor version number (Z in x.y.Z) + alias: Boost_SUBMINOR_VERSION + Boost_VERSION_COUNT - Amount of version components (3) + Boost_LIB_DIAGNOSTIC_DEFINITIONS (Windows) + - Pass to add_definitions() to have diagnostic + information about Boost's automatic linking + displayed during compilation + +Note that Boost Python components require a Python version suffix +(Boost 1.67 and later), e.g. ``python36`` or ``python27`` for the +versions built against Python 3.6 and 2.7, respectively. This also +applies to additional components using Python including +``mpi_python`` and ``numpy``. Earlier Boost releases may use +distribution-specific suffixes such as ``2``, ``3`` or ``2.7``. +These may also be used as suffixes, but note that they are not +portable. + +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_RELEASE - Directory containing release Boost libraries + Boost_LIBRARY_DIR_DEBUG - Directory containing debug Boost libraries + Boost_<C>_LIBRARY_DEBUG - Component <C> library debug variant + Boost_<C>_LIBRARY_RELEASE - Component <C> library release variant + +The following :prop_tgt:`IMPORTED` targets are also defined:: + + Boost::headers - Target for header-only dependencies + (Boost include directory) + alias: Boost::boost + Boost::<C> - Target for specific component dependency + (shared or static library); <C> is lower- + case + Boost::diagnostic_definitions - interface target to enable diagnostic + information about Boost's automatic linking + during compilation (adds BOOST_LIB_DIAGNOSTIC) + Boost::disable_autolinking - interface target to disable automatic + linking with MSVC (adds BOOST_ALL_NO_LIB) + Boost::dynamic_linking - interface target to enable dynamic linking + linking with MSVC (adds BOOST_ALL_DYN_LINK) + +Implicit dependencies such as ``Boost::filesystem`` requiring +``Boost::system`` will be automatically detected and satisfied, even +if system is not specified when using :command:`find_package` and if +``Boost::system`` is not added to :command:`target_link_libraries`. If using +``Boost::thread``, then ``Threads::Threads`` will also be added automatically. + +It is important to note that the imported targets behave differently +than variables created by this module: multiple calls to +:command:`find_package(Boost)` in the same directory or sub-directories with +different options (e.g. static or shared) will not override the +values of the targets created by the first call. + +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 directories in ``Boost_LIBRARY_DIR_DEBUG`` and +``Boost_LIBRARY_DIR_RELEASE`` 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_DEBUG_LIBS - Set to ON or OFF to specify whether to search + and use the debug libraries. Default is ON. + Boost_USE_RELEASE_LIBS - Set to ON or OFF to specify whether to search + and use the release libraries. Default is ON. + 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. A list may be + used if multiple compatible suffixes should + be tested for, in decreasing order of + preference. + Boost_LIB_PREFIX - Set to the platform-specific library name + prefix (e.g. "lib") used by Boost static libs. + This is needed only on platforms where CMake + does not know the prefix by default. + Boost_ARCHITECTURE - Set to the architecture-specific library suffix + (e.g. "-x64"). 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_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.1.67.0" instead of + "/usr/lib/libboost_system.so". This does not + affect linking and should not be enabled unless + the user needs this information. + Boost_LIBRARY_DIR - Default value for Boost_LIBRARY_DIR_RELEASE and + Boost_LIBRARY_DIR_DEBUG. + +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``).
