+# 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. 1.67.0
+#     [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"
+#     [OPTIONAL_COMPONENTS <libs>...]
+#                            # Optional 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
+#
+# 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::boost                  - Target for header-only dependencies
+#                                   (Boost include directory)
+#   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 find_package and if
+# Boost::system is not added to 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
+# 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_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.1.67.0" 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).  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 libraries and use imported targets::
+#
+#   find_package(Boost 1.56 REQUIRED COMPONENTS
+#                date_time filesystem iostreams)
+#   add_executable(foo foo.cc)
+#   target_link_libraries(foo Boost::date_time Boost::filesystem
+#                             Boost::iostreams)
+#
+# Example to find Boost Python 3.6 libraries and use imported targets::
+#
+#   find_package(Boost 1.67 REQUIRED COMPONENTS
+#                python36 numpy36)
+#   add_executable(foo foo.cc)
+#   target_link_libraries(foo Boost::python36 Boost::numpy36)
+#
+# Example to find Boost headers and some *static* (release only) libraries::
+#
+#   set(Boost_USE_STATIC_LIBS        ON)  # only find static libs
+#   set(Boost_USE_DEBUG_LIBS         OFF) # ignore debug libs and
+#   set(Boost_USE_RELEASE_LIBS       ON)  # only find release libs
+#   set(Boost_USE_MULTITHREADED      ON)
+#   set(Boost_USE_STATIC_RUNTIME    OFF)
+#   find_package(Boost 1.66.0 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
