ASIO C-ARES is a C++14 library which allows the use of libcares with Boost.Asio. No need to manage select just use the provided composed asynchronous operations and run a boost::asio::io_service.

1. Create an asio_cares::library object (an RAII wrapper for libcares global initialization/cleanup)
2. Create an asio_cares::channel object
3. Dispatch one or more questions on the channel using async_send
4. Call async_process or call async_process_one until done returns true

Other libraries are depended on, but are header only and are downloaded by CMake:

• Beast
• Catch
• MPark Variant

• Clang 4+ or GCC 6.2.0+ or Microsoft Visual C++ 2017+ (may work with earlier compilers, these are the oldest used for CI)
• CMake 3.5+
