=head1 NAME
Alien::Build::Plugin::Build::SearchDep - Add dependencies to library and header search path
=head1 VERSION
version 2.29
=head1 SYNOPSIS
use alienfile;
plugin 'Build::SearchDep' => (
aliens => [qw( Alien::Foo Alien::Bar )],
);
=head1 DESCRIPTION
This plugin adds the other aliens as prerequisites, and adds their header and library
search path to C<CFLAGS> and C<LDFLAGS> environment variable, so that tools that use
them (like autoconf) can pick them up.
=head1 PROPERTIES
=head2 aliens
Either a list reference or hash reference of the other aliens. If a hash reference
then the keys are the class names and the values are the versions of those classes.
=head2 public_I
Include the C<-I> flags when setting the runtime cflags property.
=head2 public_l
Include the C<-l> flags when setting the runtime libs property.
