# #
# boost_library_project: Defines a Boost library project (e.g., #
# Boost.Python). #
# #
# boost_add_library: Builds library binaries for Boost libraries #

add_custom_target(modularize)
# Defines a Boost library project (e.g., for Boost.Python). Use as:
#
# boost_library_project(libname
# [SRCDIRS srcdir1 srcdir2 ...]
# [TESTDIRS testdir1 testdir2 ...]
# [DEPENDS lib1 lib2 ...]
# [DESCRIPTION description]
# [AUTHORS author1 author2 ...]
# [MAINTAINERS maint1 maint2 ...]
# [MODULARIZED])
#
# where libname is the name of the library (e.g., Python, or
# Filesystem), srcdir1, srcdir2, etc, are subdirectories containing
# library sources (for Boost libraries that build actual library
# binaries), and testdir1, testdir2, etc, are subdirectories
# containing regression tests. DEPENDS lists the names of the other
# Boost libraries that this library depends on. If the dependencies
# are not satisfied (e.g., because the library isn't present or its
# build is turned off), this library won't be built.
#
# DESCRIPTION provides a brief description of the library, which can
# be used to summarize the behavior of the library for a user. AUTHORS
# lists the authors of the library, while MAINTAINERS lists the active
# maintainers. If MAINTAINERS is left empty, it is assumed that the
# authors are still maintaining the library. Both authors and maintainers
# should have their name followed by their current e-mail address in
# angle brackets, with -at- instead of the at sign, e.g.,
# Douglas Gregor <doug.gregor -at- gmail.com>
#
# For libraries that build actual library binaries, this macro adds a
# option BUILD_BOOST_LIBNAME (which defaults to ON). When the option
# is ON, this macro will include the source subdirectories, and
# therefore, will build and install the library binary.
#
# For libraries that have regression tests, and when testing is
# enabled globally by the BUILD_REGRESSION_TESTS option, this macro also
# defines the TEST_BOOST_LIBNAME option (defaults to ON). When ON, the
# generated makefiles/project files will contain regression tests for
# this library.
#
# Example:
# boost_library_project(
# Thread
# SRCDIRS src
# TESTDIRS test
# )

# naming a specific set of features for that variant, e.g.,
# STATIC:DEBUG:SINGLE_THREADED.
#
# BOOST_FEATURES:
# This variable describes all of the feature sets that we know about,
# and will be extended each time ither boost_add_default_variant or
# boost_add_extra_variant is invoked. This macro will contain a list
# of feature sets, each containing the values for a given feature
# separated by colons, e.g., "DEBUG:RELEASE".
#
# BOOST_ADD_ARG_NAMES:
# This variable describes all of the feature-specific arguments
# that can be used for the boost_add_library macro, separated by
# semicolons. For example, given the use of
# boost_add_default_variant above, this variable will contain (at
# least)
#
# SINGLE_THREADED_COMPILE_FLAGS;SINGLE_THREADED_LINK_FLAGS;
# MULTI_THREADED_COMPILE_FLAGS;MULTI_THREADED_LINK_FLAGS
#
# When this variable is used in boost_add_library, it turns these
# names into feature-specific options. For example,
# MULTI_THREADED_COMPILE_FLAGS provides extra compile flags to be
# used only for multi-threaded variants of the library.
#
# BOOST_ADDLIB_OPTION_NAMES:
# Like BOOST_ADD_ARG_NAMES, this variable describes
# feature-specific options to boost_add_library that can be used to
# turn off building of the library when the variant would require
# certain features. For example, the NO_SINGLE_THREADED option
# turns off building of single-threaded variants for a library.

# to build the library, e.g., cregex.cpp.
#
# This macro has a variety of options that affect its behavior. In
# several cases, we use the placeholder "feature" in the option name
# to indicate that there are actually several different kinds of
# options, each referring to a different build feature, e.g., shared
# libraries, multi-threaded, debug build, etc. For a complete listing
# of these features, please refer to the CMakeLists.txt file in the
# root of the Boost distribution, which defines the set of features
# that will be used to build Boost libraries by default.
#
# The options that affect this macro's behavior are:
#
# COMPILE_FLAGS: Provides additional compilation flags that will be
# used when building all variants of the library. For example, one
# might want to add "-DBOOST_SIGNALS_NO_LIB=1" through this option
# (which turns off auto-linking for the Signals library while
# building it).
#
# feature_COMPILE_FLAGS: Provides additional compilation flags that
# will be used only when building variants of the library that
# include the given feature. For example,
# MULTI_THREADED_COMPILE_FLAGS are additional flags that will be
# used when building a multi-threaded variant, while
# SHARED_COMPILE_FLAGS will be used when building a shared library
# (as opposed to a static library).
#
# LINK_FLAGS: Provides additional flags that will be passed to the
# linker when linking each variant of the library. This option
# should not be used to link in additional libraries; see LINK_LIBS
# and DEPENDS.
#
# feature_LINK_FLAGS: Provides additional flags that will be passed
# to the linker when building variants of the library that contain a
# specific feature, e.g., MULTI_THREADED_LINK_FLAGS. This option
# should not be used to link in additional libraries; see
# feature_LINK_LIBS.
#
# LINK_LIBS: Provides additional libraries against which each of the
# library variants will be linked. For example, one might provide
# "expat" as options to LINK_LIBS, to state that each of the library
# variants will link against the expat library binary. Use LINK_LIBS
# for libraries external to Boost; for Boost libraries, use DEPENDS.
#
# feature_LINK_LIBS: Provides additional libraries for specific
# variants of the library to link against. For example,
# MULTI_THREADED_LINK_LIBS provides extra libraries to link into
# multi-threaded variants of the library.
#
# DEPENDS: States that this Boost library depends on and links
# against another Boost library. The arguments to DEPENDS should be
# the unversioned name of the Boost library, such as
# "boost_filesystem". Like LINK_LIBS, this option states that all
# variants of the library being built will link against the stated
# libraries. Unlike LINK_LIBS, however, DEPENDS takes particular
# library variants into account, always linking the variant of one
# Boost library against the same variant of the other Boost
# library. For example, if the boost_mpi_python library DEPENDS on
# boost_python, multi-threaded variants of boost_mpi_python will
# link against multi-threaded variants of boost_python.
#
# MODULE: This option states that, when building a shared library,
# the shared library should be built as a module rather than a
# normal shared library. Modules have special meaning an behavior on
# some platforms, such as Mac OS X.
#
# NOT_feature: States that library variants containing a particular
# feature should not be built. For example, passing
# NOT_SINGLE_THREADED suppresses generation of single-threaded
# variants of this library.
#
# EXTRA_VARIANTS: Specifies that extra variants of this library
# should be built, based on the features listed. Each "variant" is a
# colon-separated list of features. For example, passing
# EXTRA_VARIANTS "PYTHON_NODEBUG:PYTHON_DEBUG"
# will result in the creation of an extra set of library variants,
# some with the PYTHON_NODEBUG feature and some with the
# PYTHON_DEBUG feature.
#
# FORCE_VARIANTS: This will force the build system to ALWAYS build this
# variant of the library not matter what variants are set.
#
# Example:
# boost_add_library(
# boost_thread
# barrier.cpp condition.cpp exceptions.cpp mutex.cpp once.cpp
# recursive_mutex.cpp thread.cpp tss_hooks.cpp tss_dll.cpp tss_pe.cpp

#
# feature_COMPILE_FLAGS: Provides additional compilation flags that

# shared libraries). Note that the set of features used to build the
# executable depends both on the arguments given to
# boost_add_executable (see the "feature" argument description,
# below) and on the user's choice of variants to build.
#
# LINK_FLAGS: Provides additional flags that will be passed to the
# linker when linking the executable. This option should not be used
# to link in additional libraries; see LINK_LIBS and DEPENDS.
#
# feature_LINK_FLAGS: Provides additional flags that will be passed
# to the linker when linking the executable with the given feature
# (e.g., MULTI_THREADED_LINK_FLAGS when we're linking a

#
# LINK_LIBS: Provides additional libraries against which the

# as options to LINK_LIBS, to state that the executable will link

# external to Boost; for Boost libraries, use DEPENDS.
#
# feature_LINK_LIBS: Provides additional libraries to link against
# when linking an executable built with the given feature.
#
# DEPENDS: States that this executable depends on and links against
# a Boostlibrary. The arguments to DEPENDS should be the unversioned
# name of the Boost library, such as "boost_filesystem". Like
# LINK_LIBS, this option states that the executable will link
# against the stated libraries. Unlike LINK_LIBS, however, DEPENDS
# takes particular library variants into account, always linking to
# the appropriate variant of a Boost library. For example, if the
