Subject: configure: let define pkg-config directory with `--with-pkgconfigdir`
X-Git-Tag: 0.7.13~1
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=135ff0f7fabb8f6192e86acbf72e20f50a0bd0e7;p=thirdparty%2Flldpd.git

configure: let define pkg-config directory with `--with-pkgconfigdir`

This needs a recent version of pkg.m4. However, we provide a fallback if
not present.

Closes: #87
