Subject: meson: allow customize perl installation path
X-Git-Tag: v2.50.0-rc0~39^2
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=5463c1d4f6d03e63ee79bd822de667090f015356;p=thirdparty%2Fgit.git

meson: allow customize perl installation path

Some distros, notably Fedora, want to install non-core Perl libraries
into specific directory, namely /usr/share/perl5/vendor_perl.

The Makefile build system allows this by overriding perllibdir variable,
let's make meson works on par with our Makefile.
