NAME
    Alien::cares - find or build the c-ares asynchronous DNS resolver
    library

SYNOPSIS
    In an XS distribution's Makefile.PL, using Alien::Base::Wrapper:

        use ExtUtils::MakeMaker;
        use Alien::Base::Wrapper qw( Alien::cares !export );

        WriteMakefile(
            Alien::Base::Wrapper->mm_args,
            NAME               => 'My::Module',
            CONFIGURE_REQUIRES => {
                'Alien::Base::Wrapper' => 0,
                'Alien::cares'         => 0,
            },
            PREREQ_PM => { 'Alien::cares' => 0 },
        );

    Or, accessing the flags directly:

        use Alien::cares;
        INC  => Alien::cares->cflags,
        LIBS => [ Alien::cares->libs ],

    In another distribution's alienfile:

        use alienfile;
        share { requires 'Alien::cares' };

DESCRIPTION
    Alien::cares finds or builds the c-ares <https://c-ares.org/> C library,
    which provides asynchronous DNS resolution. The dual install strategy
    follows the Alien::Base convention:

    *   A system-installed c-ares >= 1.22.0 detected via "pkg-config" is
        used directly (*system* install).

    *   Otherwise the latest release tarball is downloaded from GitHub and
        built with CMake as a static library bundled with this distribution
        (*share* install).

    Set the "ALIEN_INSTALL_TYPE" environment variable to "system" or "share"
    to force a particular install type.

METHODS
    This module inherits all methods from Alien::Base. The most useful ones
    are "cflags", "libs", "libs_static", "version", and "install_type".
