Newer cmake uses a different module to find python.

Now onto poco which doesn't seem available for aarm64 on brew.

Edit: poco not pogo

brew install --build-from-source poco

Smooth sailing from then on.

Can someone provide a binary for M1? I'm running a 256GB base model and I'm already low on disk space. So I would like to avoid installing all the dependencies.

@tristan-k I recommend using the regular amd64 version with rosetta. The native build still has a lot of problems that make it pretty unusable (crashes when switching audio devices, no hotkey support, …)
See „Caveats“ here: mumble-voip/mumble#4765

Thanks for the heads-up. I guess will have to wait then. If you need someone for testing just holler.
