Subject: configure: Fix check for libunbound to require v1.5.0 as minimum.
X-Git-Tag: 14.0.0-beta1~637^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=ca030845ff2f46ad51d08e47d7664ff3dc24460c;p=thirdparty%2Fasterisk.git

configure: Fix check for libunbound to require v1.5.0 as minimum.

Versions of libunbound before v1.4.21 do not compile with Asterisk.
However, since v1.4.21 has a configure script bug that fails to detect the
ldns library (which is fixed in v1.4.22) and v1.4.22 is not an easily
detectable version we will require v1.5.0 as a minimum version of the
library to work with Asterisk.
