tdf#108580 ship universal crts with the program as workaround

the universal crts redistributables are available as part of the Windows
10 SDK. Point to the dir (or a copy of the dir) using --with-ucrt-dir

Use --without-ucrt-dir (or --with-ucrt-dir=no) if you don't want to ship
them as part of LO and are annoyed by the configure warning.
