       ExtUtils::PkgConfig - simplistic interface to pkg-config

SYNOPSIS

        use ExtUtils::PkgConfig;

        $package = 'gtk+-2.0';

        %pkg_info = ExtUtils::PkgConfig->find ($package);
        print "modversion:  $pkg_info{modversion}\n";
        print "cflags:      $pkg_info{cflags}\n";
        print "libs:        $pkg_info{libs}\n";

        $exists = ExtUtils::PkgConfig->exists($package);

        $modversion = ExtUtils::PkgConfig->modversion($package);

        $libs = ExtUtils::PkgConfig->libs($package);

        $cflags = ExtUtils::PkgConfig->cflags($package);

        $cflags_only_I = ExtUtils::PkgConfig->cflags_only_I($package);

        $cflags_only_other = ExtUtils::PkgConfig->cflags_only_other($package);

        $libs_only_L = ExtUtils::PkgConfig->libs_only_L($package);

        $libs_only_l = ExtUtils::PkgConfig->libs_only_l($package);

        $libs_only_other = ExtUtils::PkgConfig->libs_only_other($package);

        $static_libs = ExtUtils::PkgConfig->static_libs($package);

        $var_value = ExtUtils::PkgConfig->variable($package, $var);

        if (ExtUtils::PkgConfig->atleast_version($package,$version)) {
           ...
        }

        if (ExtUtils::PkgConfig->exact_version($package,$version)) {
           ...
        }

        if (ExtUtils::PkgConfig->max_version($package,$version)) {
           ...
        }

DESCRIPTION

       The pkg-config program retrieves information about installed libraries, usually for the purposes of
       compiling against and linking to them.

       ExtUtils::PkgConfig is a very simplistic interface to this utility, intended for use in the Makefile.PL
       of perl extensions which bind libraries that pkg-config knows.  It is really just boilerplate code that
       you would've written yourself.

   USAGE
       HASH = ExtUtils::PkgConfig->find (STRING, [STRING, ...])
           Call pkg-config on the library specified by STRING (you'll have to know what to use here).  The
           returned HASH contains the modversion, cflags, and libs values under keys with those names. If
           multiple STRINGS are passed they are attempted in the order they are given till a working package is
           found.

           If pkg-config fails to find a working STRING, this function croaks with a message intended to be
           helpful to whomever is attempting to compile your package.

           For example:

             *** can not find package bad1
             *** check that it is properly installed and available
             *** in PKG_CONFIG_PATH

           or

             *** can't find cflags for gtk+-2.0
             *** is it properly installed and available in PKG_CONFIG_PATH?

       STRING = ExtUtils::PkgConfig->create_version_macros (PACKAGE, STEM)
           Create a set of version macros with the prefix STEM for the library specified by PACKAGE.  The result
           is returned.

           Example input would be "gtk+-2.0" for PACKAGE and "GTK" for STEM.

       ExtUtils::PkgConfig->write_version_macros (FILE, PACKAGE, STEM, [PACKAGE, STEM, ...])
           Create one or more sets of version macros for the libraries and prefixes specified by the PACKAGE and
           STEM pairs and write them to the file FILE.  If it doesn't exist, FILE will be created.  If it does
           exist, it will be overwritten.

SEE ALSO

       ExtUtils::PkgConfig was designed to work with ExtUtils::Depends for compiling the various modules of the
       gtk2-perl project.

       This module is really just an interface to the pkg-config utility program.
