Subject: build: Don't link with -lreadline if readline was not found.
X-Git-Tag: v0.5.2~6^2
X-Git-Url: http://git.tuebingen.mpg.de/?p=paraslash.git;a=commitdiff_plain;h=448c8f8e8c1c1eeb88ae468c0c3ab25bed6f2ac8;hp=448c8f8e8c1c1eeb88ae468c0c3ab25bed6f2ac8

build: Don't link with -lreadline if readline was not found.

Currently, if libreadline is not installed, linking fails with

	ld: cannot find -lreadline

This patch makes the build succeed by linking para_client, para_audioc
and para_play without readline support in this case.
