# - 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).
