I would like to test this with a newer ICU version.

So I managed to setup the build environment with Visual Studio, but I can't figure out how to enable ICU for the build.

I created a config.pl to specify the location of the downloaded ICU libraries with the following content

# Configuration arguments for vcbuild.
use strict;
use warnings;

our $config = {
icu => "d:\Projects\postgres\libs\icu\lib64\" # --with-icu=<path>
};

The build is successful, but when I run "install targetfolder" no ICU libraries are included and pg_config only shows:

CONFIGURE = --enable-thread-safety --with-ldap --without-zlib

I have no idea what I am missing.

I also tried building with Msys2 but even when I run configure with the --with-icu option, no ICU DLLs are copied
