# Copyright 2018 Mike Dev
# Copyright 2019 Peter Dimov
# Distributed under the Boost Software License, Version 1.0.
# See accompanying file LICENSE_1_0.txt or copy at https://www.boost.org/LICENSE_1_0.txt
#
# NOTE: CMake support for Boost.Regex is currently experimental at best
# and the interface is likely to change in the future
# See accompanying file LICENSE_1_0.txt or copy at http://www.boost.org/LICENSE_1_0.txt
# We support CMake 3.5, but prefer 3.16 policies and behavior
cmake_minimum_required(VERSION 3.5...3.16)
##### How-To:
#
# If you have a cmake project that wants to use and compile
# boost_regex, as part of a single build system run, do the following:
# 1) clone the boost project and all its sub-projects:
#
# git clone --branch develop --depth 1 --recursive --shallow-submodules https://github.com/boostorg/boost.git boost-root
#
# 2) add to your cmake script:
#
# add_subdirectory( <path-to-boost-root> [<build-dir-for-boost-libs>])
# target_link_libraries( <my-exec> PUBLIC Boost::regex)
#
# 3) run your cmake build as usual
#
# ## Explanation:
#
# Currently this file does not work standalone. It is expected to be
# invoked from a parent script via add_subdirectory. That parent script
# is responsible for providing targets for direct and indirect dependencies,
# such as Boost::assert, Boost::concept_check, e.g. by also adding those
# libraries via add_submodule (order doesn't matter).
# The parent script can be your own cmake script, but it is easier to just
# use add the CMakeLists in the root of the boost super project, which
# will in turn add all boost libraries usable with the add_subdirectory
# Workflow.
#
# Note: You don't need to actually clone all boost libraries. E.g. look
# into the travis ci file to see on which libraries boost_regex actually
# depends or use boostdep https://github.com/boostorg/boostdep

[section:standalone Use in Standalone Mode (without the rest of Boost)]
This library may now be used in "standalone" mode without the rest of the Boost C++ libraries,
in order to do this you must either:
* Have a C++17 compiler that supports `__has_include`, in this case if `<boost/config.hpp>` is *not* present
then the library will automoatically enter standalone mode. Or:
* Define BOOST_REGEX_STANDALONE when building.
The main difference between the 2 modes, is that when Boost.Config is present the library will automatically
configure itself around various compiler defects. In particular in order to use the library with exception support
turned off, you will either need a copy of Boost.Config in your include path, or else manually define BOOST_NO_EXCEPTIONS
when building.
