Split boost dependency out into separate file Boost dependency is very complex and it is easier to manage it in a separate file.

# On windows 3 directory layouts are supported:
# * The default layout (versioned) installed:
# - $BOOST_ROOT/include/boost-x_x/boost/*.hpp
# - $BOOST_ROOT/lib/*.lib
# * The non-default layout (system) installed:
# - $BOOST_ROOT/include/boost/*.hpp
# - $BOOST_ROOT/lib/*.lib
# * The pre-built binaries from sf.net:
# - $BOOST_ROOT/boost/*.hpp
# - $BOOST_ROOT/lib<arch>-<compiler>/*.lib where arch=32/64 and compiler=msvc-14.1
#
# Note that we should also try to support:
# mingw-w64 / Windows : libboost_<module>-mt.a (location = <prefix>/mingw64/lib/)
# libboost_<module>-mt.dll.a
#
# Library names supported:
# - libboost_<module>-<compiler>-mt-gd-x_x.lib (static)
# - boost_<module>-<compiler>-mt-gd-x_x.lib|.dll (shared)
# - libboost_<module>.lib (static)
# - boost_<module>.lib|.dll (shared)
# where compiler is vc141 for example.
#
# NOTE: -gd means runtime and build time debugging is on
# -mt means threading=multi
#
# The `modules` argument accept library names. This is because every module that
# has libraries to link against also has multiple options regarding how to
# link. See for example:
# * http://www.boost.org/doc/libs/1_65_1/libs/test/doc/html/boost_test/usage_variants.html
# * http://www.boost.org/doc/libs/1_65_1/doc/html/stacktrace/configuration_and_build.html
# * http://www.boost.org/doc/libs/1_65_1/libs/math/doc/html/math_toolkit/main_tr1.html
# **On Unix**, official packaged versions of boost libraries follow the following schemes:
#
# Linux / Debian: libboost_<module>.so -> libboost_<module>.so.1.66.0
# Linux / Red Hat: libboost_<module>.so -> libboost_<module>.so.1.66.0
# Linux / OpenSuse: libboost_<module>.so -> libboost_<module>.so.1.66.0
# Win / Cygwin: libboost_<module>.dll.a (location = /usr/lib)
# libboost_<module>.a
# cygboost_<module>_1_64.dll (location = /usr/bin)
# Mac / homebrew: libboost_<module>.dylib + libboost_<module>-mt.dylib (location = /usr/local/lib)
# Mac / macports: libboost_<module>.dylib + libboost_<module>-mt.dylib (location = /opt/local/lib)
#
# Its not clear that any other abi tags (e.g. -gd) are used in official packages.
#
# On Linux systems, boost libs have multithreading support enabled, but without the -mt tag.
#
# Boost documentation recommends using complex abi tags like "-lboost_regex-gcc34-mt-d-1_36".
# (See http://www.boost.org/doc/libs/1_66_0/more/getting_started/unix-variants.html#library-naming)
# However, its not clear that any Unix distribution follows this scheme.
# Furthermore, the boost documentation for unix above uses examples from windows like
# "libboost_regex-vc71-mt-d-x86-1_34.lib", so apparently the abi tags may be more aimed at windows.
#
# Probably we should use the linker search path to decide which libraries to use. This will
# make it possible to find the macports boost libraries without setting BOOST_ROOT, and will
# also mean that it would be possible to use user-installed boost libraries when official
# packages are installed.
#
# We thus follow the following strategy:
# 1. Look for libraries using compiler.find_library( )
# 1.1 On Linux, just look for boost_<module>
# 1.2 On other systems (e.g. Mac) look for boost_<module>-mt if multithreading.
# 1.3 Otherwise look for boost_<module>
# 2. Fall back to previous approach
# 2.1. Search particular directories.
# 2.2. Find boost libraries with unknown suffixes using file-name globbing.
# TODO: Unix: Don't assume we know where the boost dir is, rely on -Idir and -Ldir being set.
# TODO: Allow user to specify suffix in BOOST_SUFFIX, or add specific options like BOOST_DEBUG for 'd' for debug.
