Default is ``OFF``. + +``Boost_ADDITIONAL_VERSIONS`` + List of Boost versions not known to this module. + (Boost install locations may contain the version). + +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_<COMPONENT>_LIBRARY_DEBUG`` and ``Boost_<COMPONENT>_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. + +Imported Targets +^^^^^^^^^^^^^^^^ + +.. versionadded:: 3.5 + +This module defines the following :prop_tgt:`IMPORTED` targets: + +``Boost::boost`` + Target for header-only dependencies. (Boost include directory). + +``Boost::headers`` + .. versionadded:: 3.15 + Alias for ``Boost::boost``. + +``Boost::<component>`` + Target for specific component dependency (shared or static library); + ``<component>`` name is lower-case. + +``Boost::diagnostic_definitions`` + Interface target to enable diagnostic information about Boost's automatic + linking during compilation (adds ``-DBOOST_LIB_DIAGNOSTIC``). + +``Boost::disable_autolinking`` + Interface target to disable automatic linking with MSVC + (adds ``-DBOOST_ALL_NO_LIB``). + +``Boost::dynamic_linking`` + Interface target to enable dynamic linking with MSVC + (adds ``-DBOOST_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. + +Other Variables +^^^^^^^^^^^^^^^ + +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`` + .. versionadded:: 3.10 + + Set to ``ON`` or ``OFF`` to specify whether to search and use the debug + libraries. Default is ``ON``. + +``Boost_USE_RELEASE_LIBS`` + .. versionadded:: 3.10 + + 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. + + .. versionchanged:: 3.9 + A list may be used if multiple compatible suffixes should be tested for, + in decreasing order of preference. + +``Boost_LIB_PREFIX`` + .. versionadded:: 3.18 + + 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`` + .. versionadded:: 3.13 + + 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``. + +``Boost_NO_WARN_NEW_VERSIONS`` + .. versionadded:: 3.20 + + Set to ``ON`` to suppress the warning about unknown dependencies for new + Boost versions. + +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``).
