# 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
#
# 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

# **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)
# Win   / VS:       boost_<module>-vc<ver>-mt[-gd]-<arch>-1_67.dll          (location = C:/local/boost_1_67_0)
# 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.
#
# We follow the following strategy for finding modules:
# A) Detect potential boost root directories (uses also BOOST_ROOT env var)
# B) Foreach candidate
#   1. Look for the boost headers (boost/version.pp)
#   2. Find all boost libraries
#     2.1 Add all libraries in lib*
#     2.2 Filter out non boost libraries
#     2.3 Filter the renaining libraries based on the meson requirements (static/shared, etc.)
#     2.4 Ensure that all libraries have the same boost tag (and are thus compatible)
#   3. Select the libraries matching the requested modules
