# This file is used to factor out a common pattern in builtin.mk files backed
# up by the existence of a pkgconfig file.
#
# Caller has to define BUILTIN_PKG and PKGCONFIG_FILE.<BUILTIN_PKG>.
#
# Optionally, caller may define PKGCONFIG_BASE.<BUILTIN_PKG> as the base
# location for a native implementation of the package.  It conveniently
# defaults to X11BASE.
#
# The caller may also override the default, pkgconfig-specific, version
# script.  That means this file can be called by a lot more generic
# builtin.mk files.
