-#     )                      # 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
