If MINIMUM-VERSION +# is specified, the script must also support the `--version' arg. If the +# `--with-library-[exec-]prefix' arguments to ./configure are given, it +# must also support `--prefix' and `--exec-prefix'. Prefereable use +# CONFIG-SCRIPTS as config script, CFLAGS-ARG instead of `--cflags` and +# LIBS-ARG instead of `--libs`, if given. +# +# The SED-EXPR-EXTRACTOR parameter representes the expression used in sed +# to extract the version number. Use it if your 'foo-config --version' +# dumps something like 'Foo library v1.0.0 (alfa)' instead of '1.0.0'. +# +# Example: +# +# AX_PATH_GENERIC(Foo, 1.0.0) +# +# would run `foo-config --version' and check that it is at least 1.0.0, if +# successful the following variables would be defined and substituted: +# +# FOO_CFLAGS to `foo-config --cflags` +# FOO_LIBS to `foo-config --libs` +# +# Example: +# +# AX_PATH_GENERIC([Bar],,,[ +# AC_MSG_ERROR([Cannot find Bar library]) +# ]) +# +# would check for bar-config program, defining and substituting the +# following variables: +# +# BAR_CFLAGS to `bar-config --cflags` +# BAR_LIBS to `bar-config --libs` +# +# This macro is a rearranged version of AC_PATH_GENERIC from Angus Lees. +# +# LICENSE +# +# Copyright (c) 2009 Francesco Salvestrini <salvestrini@users.sourceforge.net> +# +# Copying and distribution of this file, with or without modification, are +# permitted in any medium without royalty provided the copyright notice +# and this notice are preserved.
