-# 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.

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 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".
