rules_boost -- Bazel build rules for Boost

To use these rules, add the following to your WORKSPACE file:

load("@bazel_tools//tools/build_defs/repo:git.bzl", "git_repository")

git_repository(
    name = "com_github_nelhage_rules_boost",
    commit = "1e3a69bf2d5cd10c34b74f066054cd335d033d71",
    remote = "https://github.com/nelhage/rules_boost",
    shallow_since = "1591047380 -0700",
)

load("@com_github_nelhage_rules_boost//:boost/boost.bzl", "boost_deps")
boost_deps()

You can then use libraries in deps through the @boost repository, for example @boost//:algorithm.

Based in part on rules from https://github.com/mzhaom/trunk.

ASIO SSL support

These rules implement support for Boost ASIO's SSL support. To use ASIO-SSL, you must depend on the "@boost//:asio_ssl" target, instead of "@boost//:asio". ASIO-SSL depends on OpenSSL; By default, rules_boost will download and build a recent BoringSSL commit; To use a different OpenSSL implementation, create a remote named openssl before calling boost_deps. This remote must make available OpenSSL's libssl at @openssl//:ssl.
