=head1 NAME

Alien::Build::Plugin::Build::Make - Make plugin for Alien::Build

=head1 VERSION

version 1.42

=head1 SYNOPSIS

 use alienfile;
 # For a recipe that requires GNU Make
 plugin 'Build::Make' => 'gmake';

=head1 DESCRIPTION

By default L<Alien::Build> provides a helper for the C<make> that is used by Perl and L<ExtUtils::MakeMaker> itself.
This is handy, because it is the one make that you can mostly guarantee that you will have.  Unfortunately it may be
a C<make> that isn't supported by the library or tool that you are trying to alienize.  This is mostly a problem on
Windows, where the supported C<make>s for years were Microsoft's C<nmake> and Sun's C<dmake>, which many open source
projects do not use.  This plugin will alter the L<alienfile> recipe to use a different C<make>.  It may (as in the
case of C<gmake> / L<Alien::gmake>) automatically download and install an alienized version of that C<make> if it
is not already installed.

This plugin should NOT be used with other plugins that replace the C<make> helper, like 
L<Alien::Build::Plugin::Build::CMake>, L<Alien::Build::Plugin::Build::Autoconf>, 
L<Alien::Build::Plugin::Build::MSYS>.  This plugin is intended instead for projects that use vanilla makefiles of
a specific type.

This plugin is for now distributed separately from L<Alien::Build>, but the intention is for it to soon become
a core plugin for L<Alien::Build>.

=head1 PROPERTIES

=head2 make_type

The make type needed by the L<alienfile> recipe:

=over 4

=item dmake

=item gmake

=item nmake

=item umake

Any UNIX C<make>  Usually either BSD or GNU Make.

=back

=head1 HELPERS

This plugin may change the make helper used by your L<alienfile> recipe.
