Cannot find libmilter library

[Torxed]

Expectation:

RUN cmake .. -DWITH_MILTER=ON should produce a binary that is happy to have milter enabled.
However, when attempting to run it outputs:

[root@f2f03071d763 build]# /usr/bin/postsrsd -C /etc/postsrsd/postsrsd.conf
postsrsd: error: no milter support

This used to work, so not entirely sure what changed.
Here's the full build traceback (pardon the docker padding and stuff, trying to isolate the build):

Here's the Dockerfile where I attempt to build postsrsd:

# syntax = docker/dockerfile:1.4

FROM archlinux/archlinux:latest

RUN pacman -Sy
RUN pacman -S --noconfirm gcc cmake automake make automake help2man glibc git tree libmilter diffutils

RUN mkdir -p /etc/postsrsd/
RUN mkdir -p /usr/share/doc
RUN dd if=/dev/urandom bs=18 count=1 status=none | base64 > /etc/postsrsd/postsrsd.secret

RUN mkdir -p /build/postsrsd
RUN git clone https://github.com/roehling/postsrsd.git /build/postsrsd

WORKDIR /build/postsrsd
RUN mkdir build fakeroot

WORKDIR /build/postsrsd/build

RUN cmake .. -DCMAKE_INSTALL_PREFIX=/usr -DCMAKE_BUILD_TYPE=Release -DGENERATE_SRS_SECRET=OFF -DCONFIG_DIR=/etc/postsrsd -DINIT_FLAVOR=systemd -DWITH_MILTER=ON -DDEVELOPER_BUILD=ON
RUN make all

RUN make DESTDIR="/build/postsrsd/fakeroot/" install

Partial issue related to aclocal appears to be /postsrsd/src/postsrsd-2.0.10/build/_deps/confuse-src/ are generated for automake 1.16.

cd _deps/confuse-src/ 
autoreconf --force --install
cd ../..

appears to be a workaround

Any help would be grately appreciated.
