Re: [Csnd-dev] [EXTERNAL] Re: [Csnd-dev] New API - updates

I'm having trouble building Csound at the moment. Is there any way for
someone that has the builds working or an automated system to provide DLLs
for: (1) 64-bit Windows, (2) 64-bit Ubuntu, (3) Apple silicon macOS, (4)
Raspberry Pi 4?

Would it be helpful to have a Docker process(es), if there aren't already,
build an export of the DLLs? Maybe I could help with that upon guidance
(not on Docker but on Csound build processes)?
