 +# 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_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.
 +# 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 libraries:
 +#  set(Boost_USE_STATIC_LIBS        ON)
 +#  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.
