# $NetBSD: pkgconfig-builtin.mk,v 1.8 2024/01/13 20:26:47 riastradh Exp $

# This file is used to factor out a common pattern in builtin.mk files
# that use pkgconfig files to check for a built-in implementation.
#
# Parameters:
#
# BUILTIN_PKG
#	The name of the package that is tested.
#
# PKGCONFIG_FILE.<BUILTIN_PKG>
#	The absolute path where the pkgconfig file of the native
#	implementation of the package is stored.
#
#	Example: ${X11BASE}/lib/pkgconfig/present.pc
#
# PKGCONFIG_BASE.<BUILTIN_PKG> (optional)
#	The base location for a native implementation of the package.
#
#	Default: ${X11BASE}
#
# BUILTIN_VERSION_SCRIPT.<BUILTIN_PKG> (optional)
#	The program that is used to extract the version number from the
#	PKGCONFIG_FILE.<BUILTIN_PKG>. The expected output is the plain
#	version number on a single line.
#
#	By defining a custom script this file can be called by a lot
#	more generic builtin.mk files.
#
#	Default: (something suitable for pkgconfig files)
#
