Cairo: Please test mingw installer

[Knut Petersen]

Hi everybody!


I had some time and had a look at GUB. I managed to build a mingw installer of 
lilypond + cairo backend. Gub succeeded, but that does not mean a lot ;-)

I do not have access to a PC with a MS Windows installation, so it would be 
nice if a few people could test this installer.

Download lilypond-2.23.4-1.mingw.exe 
<https://drive.google.com/file/d/1lZcrZW_qQhfNFFPfWNxiT6PV9qYmGsRf/view?usp=sharing>

Any combination of '--ps', '--pdf', '--svg',  and '--png' should work in 
combination with the '-dbackend=cairo' command line option.

Please report success / failure and the windows version you use.


Thanks,

Knut
