# This file contains pkg-config generation rules for Automake.
#
# This file assumes that:
#
# - you include *before* this file init.mk or make sure that any global
# variable can be used with the += syntax.
# - there is no other rule using install-data-local and uninstall-data-local.
#
# The generate pkg-config files can be customized using three Autoconf
# variables:
# - PKGCONFIG_REQUIRES: package dependencies,
# - PKGCONFIG_LIBS: package LDFLAGS,
# - PKGCONFIG_CFLAGS: package CFLAGS/CPPFLAGS/CXXFLAGS.


# Variables
pkg_config_file = '@PACKAGE_TARNAME@.pc'

# One has to make sure the ``.pc'' file is regenerated if:
# - the package version
# - or the compilation flags
# are changed.
