This is a soversion bump. These files are linked against it:

root(a)michael:/build/ipfire-2.x# ./make.sh find-dependencies liblua-5.3.so
/build/ipfire-2.x/build/usr/sbin/haproxy
/build/ipfire-2.x/build/usr/bin/nmap
/build/ipfire-2.x/build/usr/bin/lua
/build/ipfire-2.x/build/usr/bin/dnsdist

We will need to ship all of them again.

You are not shipping the libraries at all. I am sure this isn’t what you intended :)

The pkg-config file is for development only and we do not need to ship it.

I would recommend installing everything after compiling the package.
