-# - Try to find Boost include dirs and libraries
-# Usage of this module as follows:
-#
-# NOTE: Take note of the Boost_ADDITIONAL_VERSIONS variable below.
-# Due to Boost naming conventions and limitations in CMake this find
-# module is NOT future safe with respect to Boost version numbers,
-# and may break.
-#
-# == Using Header-Only libraries from within Boost: ==
-#
-# find_package( Boost 1.36.0 )
-# if(Boost_FOUND)
-# include_directories(${Boost_INCLUDE_DIRS})
-# add_executable(foo foo.cc)
-# endif()
-#
-#
-# == Using actual libraries from within Boost: ==
-#
-# set(Boost_USE_STATIC_LIBS ON)
-# set(Boost_USE_MULTITHREADED ON)
-# set(Boost_USE_STATIC_RUNTIME OFF)
-# find_package( Boost 1.36.0 COMPONENTS date_time filesystem system ... )
-#
-# if(Boost_FOUND)
-# include_directories(${Boost_INCLUDE_DIRS})
-# add_executable(foo foo.cc)
-# target_link_libraries(foo ${Boost_LIBRARIES})
-# endif()
-#
-#
-# The components list needs to contain actual names of boost libraries only,
-# such as "date_time" for "libboost_date_time". If you're using parts of
-# Boost that contain header files only (e.g. foreach) you do not need to
-# specify COMPONENTS.
-#
-# You should provide a minimum version number that should be used. If you provide this
-# version number and specify the REQUIRED attribute, this module will fail if it
-# can't find the specified or a later version. If you specify a version number this is
-# automatically put into the considered list of version numbers and thus doesn't need
-# to be specified in the Boost_ADDITIONAL_VERSIONS variable (see below).
-#
-# NOTE for Visual Studio Users:
-# Automatic linking is used on MSVC & Borland compilers by default when
-# #including things in Boost. It's important to note that setting
-# Boost_USE_STATIC_LIBS to OFF is NOT enough to get you dynamic linking,
-# should you need this feature. Automatic linking typically uses static
-# libraries with a few exceptions (Boost.Python is one).
-#
-# Please see the section below near Boost_LIB_DIAGNOSTIC_DEFINITIONS for
-# more details. Adding a target_link_libraries() as shown in the example
-# above appears to cause VS to link dynamically if Boost_USE_STATIC_LIBS
-# gets set to OFF. It is suggested you avoid automatic linking since it
-# will make your application less portable.
-#
-# =========== The mess that is Boost_ADDITIONAL_VERSIONS (sorry?) ============
-#
-# OK, so the Boost_ADDITIONAL_VERSIONS variable can be used to specify a list of
-# boost version numbers that should be taken into account when searching
-# for Boost. Unfortunately boost puts the version number into the
-# actual filename for the libraries, so this variable will certainly be needed
-# in the future when new Boost versions are released.
-#
-# Currently this module searches for the following version numbers:
-# 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, 1.36.0, 1.36.1, 1.37, 1.37.0, 1.38, 1.38.0, 1.39, 1.39.0,
-# 1.40, 1.40.0, 1.41, 1.41.0, 1.42, 1.42.0, 1.43, 1.43.0, 1.44, 1.44.0,
-# 1.45, 1.45.0, 1.46, 1.46.0, 1.46.1, 1.47, 1.47.0, 1.48, 1.48.0,
-# 1.49, 1.49.0, 1.50, 1.50.0, 1.51, 1.51.0, 1.52, 1.52.0,
-# 1.53, 1.53.0, 1.54, 1.54.0, 1.55, 1.55.0, 1.56, 1.56.0
-#
-# NOTE: If you add a new major 1.x version in Boost_ADDITIONAL_VERSIONS you should
-# add both 1.x and 1.x.0 as shown above. Official Boost include directories
-# omit the 3rd version number from include paths if it is 0 although not all
-# binary Boost releases do so.
-#
-# set(Boost_ADDITIONAL_VERSIONS "1.78" "1.78.0" "1.79" "1.79.0")

-# ===================================== ============= ========================
-#
-# Variables used by this module, they can change the default behaviour and
-# need to be set before calling find_package:
-#
-# Boost_USE_MULTITHREADED Can be set to OFF to use the non-multithreaded
-# boost libraries. If not specified, defaults
-# to ON.
-#
-# Boost_USE_STATIC_LIBS Can be set to ON to force the use of the static
-# boost libraries. Defaults to OFF.
-#
-# Boost_NO_SYSTEM_PATHS Set to TRUE to suppress searching in system
-# paths (or other locations outside of BOOST_ROOT
-# or BOOST_INCLUDEDIR). Useful when specifying
-# BOOST_ROOT. Defaults to OFF.
-# [Since CMake 2.8.3]
-#
-# Boost_NO_BOOST_CMAKE Do not do a find_package call in config mode
-# before searching for a regular boost install.
-# This will avoid finding boost-cmake installs.
-# Defaults to OFF.
-# [Since CMake 2.8.6]
-#
-# Boost_USE_STATIC_RUNTIME If enabled, searches for boost libraries
-# linked against a static C++ standard library
-# ('s' ABI tag). This option should be set to
-# ON or OFF because the default behavior
-# if not specified is platform dependent
-# for backwards compatibility.
-# [Since CMake 2.8.3]
-#
-# Boost_USE_DEBUG_PYTHON If enabled, searches for boost libraries
-# compiled against a special debug build of
-# Python ('y' ABI tag). Defaults to OFF.
-# [Since CMake 2.8.3]
-#
-# Boost_USE_STLPORT If enabled, searches for boost libraries
-# compiled against the STLPort standard
-# library ('p' ABI tag). Defaults to OFF.
-# [Since CMake 2.8.3]
-#
-# Boost_USE_STLPORT_DEPRECATED_NATIVE_IOSTREAMS
-# If enabled, searches for boost libraries
-# compiled against the deprecated STLPort
-# "native iostreams" feature ('n' ABI tag).
-# Defaults to OFF.
-# [Since CMake 2.8.3]
-#
-# Other Variables used by this module which you may want to set.
-#
-# Boost_ADDITIONAL_VERSIONS A list of version numbers to use for searching
-# the boost include directory. Please see
-# the documentation above regarding this
-# annoying, but necessary variable :(
-#
-# Boost_DEBUG Set this to TRUE to enable debugging output
-# of FindBoost.cmake if you are having problems.
-# Please enable this before filing any bug
-# reports.
-#
-# Boost_DETAILED_FAILURE_MSG FindBoost doesn't output detailed information
-# about why it failed or how to fix the problem
-# unless this is set to TRUE or the REQUIRED
-# keyword is specified in find_package().
-# [Since CMake 2.8.0]
-#
-# Boost_COMPILER Set this to the compiler suffix used by Boost
-# (e.g. "-gcc43") if FindBoost has problems finding
-# the proper Boost installation
-#
-# Boost_THREADAPI When building boost.thread, sometimes the name of the
-# library contains an additional "pthread" or "win32"
-# string known as the threadapi. This can happen when
-# compiling against pthreads on Windows or win32 threads
-# on Cygwin. You may specify this variable and if set
-# when FindBoost searches for the Boost threading library
-# it will first try to match the threadapi you specify.
-# For Example: libboost_thread_win32-mgw45-mt-1_43.a
-# might be found if you specified "win32" here before
-# falling back on libboost_thread-mgw45-mt-1_43.a.
-# [Since CMake 2.8.3]
-#
-# Boost_REALPATH Resolves symbolic links for discovered boost libraries
-# to assist with packaging. For example, instead of
-# Boost_SYSTEM_LIBRARY_RELEASE being resolved to
-# "/usr/lib/libboost_system.so" it would be
-# "/usr/lib/libboost_system.so.1.42.0" instead.
-# This does not affect linking and should not be
-# enabled unless the user needs this information.
-# [Since CMake 2.8.3]
-#

-#
-# These last three variables are available also as environment variables:
-# Also, note they are completely UPPERCASE, except Boost_DIR.
-#
-# Boost_DIR or The preferred installation prefix for searching for
-# BOOST_ROOT or BOOSTROOT Boost. Set this if the module has problems finding
-# the proper Boost installation.
-#
-# Note that Boost_DIR behaves exactly as <package>_DIR
-# variables are documented to behave in find_package's
-# Config mode. That is, if it is set as a -D argument
-# to CMake, it must point to the location of the
-# BoostConfig.cmake or Boost-config.cmake file. If it
-# is set as an environment variable, it must point to
-# the root of the boost installation. BOOST_ROOT and
-# BOOSTROOT, on the other hand, will point to the root
-# in either case.
-#
-# To prevent falling back on the system paths, set
-# Boost_NO_SYSTEM_PATHS to true.
-#
-# To avoid finding boost-cmake installations, set
-# Boost_NO_BOOST_CMAKE to true.
-#
-# BOOST_INCLUDEDIR Set this to the include directory of Boost, if the
-# module has problems finding the proper Boost installation
-#
-# BOOST_LIBRARYDIR Set this to the lib directory of Boost, if the
-# module has problems finding the proper Boost installation
-#
-# Variables defined by this module:
-#
-# Boost_FOUND System has Boost, this means the include dir was
-# found, as well as all the libraries specified in
-# the COMPONENTS list.
-#
-# Boost_INCLUDE_DIRS Boost include directories: not cached
-#
-# Boost_INCLUDE_DIR This is almost the same as above, but this one is
-# cached and may be modified by advanced users
-#
-# Boost_LIBRARIES Link to these to use the Boost libraries that you
-# specified: not cached
-#
-# Boost_LIBRARY_DIRS The path to where the Boost library files are.
-#
-# Boost_VERSION The version number of the boost libraries that
-# have been found, same as in version.hpp from Boost
-#
-# Boost_LIB_VERSION The version number in filename form as
-# it's appended to the library filenames
-#
-# Boost_MAJOR_VERSION major version number of boost
-# Boost_MINOR_VERSION minor version number of boost
-# Boost_SUBMINOR_VERSION subminor version number of boost
-#
-# Boost_LIB_DIAGNOSTIC_DEFINITIONS [WIN32 Only] You can call
-# add_definitions(${Boost_LIB_DIAGNOSTIC_DEFINITIONS})
-# to have diagnostic information about Boost's
-# automatic linking outputted during compilation time.
-#
-# For each component you specify in find_package(), the following (UPPER-CASE)
-# variables are set. You can use these variables if you would like to pick and
-# choose components for your targets instead of just using Boost_LIBRARIES.
-#
-# Boost_${COMPONENT}_FOUND True IF the Boost library "component" was found.
-#
-# Boost_${COMPONENT}_LIBRARY Contains the libraries for the specified Boost
-# "component" (includes debug and optimized keywords
-# when needed).
+# - 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 the 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.
