1. full tarball https://github.com/wineasio/wineasio/releases/download/v1.0.0/wineasio-1.0.0.tar.gz

2. you should give some filename-version.tar.gz (for example) to the rtaudio tarball, because set_version works only for package main source (Source0).

3. you can grab all wineasio sources (including submodules) with _services

I'm trying to build wineasio 1.0.0.[1]
The "rtaudio" folder was moved to a git submodule. How do I correctly
integrate this into the other source files? Adding a service to download the
"rtaudio" folder works, but I can't access it at build time[2].
