# 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_ARCHITECTURE - Set to the architecture-specific library suffix
# (e.g. "-x64"). 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.1.67.0" 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

# 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
