openocd: could it be compiled with CMSIS-DAPv2 enabled?

Hello,
I'm currently experimenting with CMSIS-DAPv2 for the picoprobe. During my experiments I found out, that the bundled (Windows) OpenOCD does not handle CMSIS-DAPv2.
Log should look like this:

But the bundled version shows:

Any chances to include an updated version which is fixed?
I already filed this to https://github.com/maxgerhardt/platform-raspberrypi.git. Maintainer Max Gerhardt told me, that this is the right place to go.
Specifically, this config kills it

I tried to minimize the build dependencies by stripping OpenOCD to the bare minimum. Looks like I cut a bit too deep. Due to dependencies on libUSB not quite working when cross-compiled under Linux this was built by hand on a Windows box. I'll see how it comes out and if I can automate this via a GH action instead of my (fragile) manual method and post a test exe here in a few days...
For the GD32 fork of OpenOCD in the XPack version I hacked together / massaged the Github action to run natively on the github action system: https://github.com/CommunityGD32Cores/openocd-xpack/blob/xpack-develop/.github/workflows/build.yml#L34-L81
The XPack build box system appeared to be extremely picky to me, requiring a dedicated machine, it built its own toolchain, requiring an actual Mac custom runner for doing Mac builds. I had time for none of that so I had the github actions machine execute the builds that it could make directly, see xpack/xpack-build-box#3 (reply in thread).
@rgrr, can you give this a try: openocd.zip
I ran it on a clean Win64 system (no msys/etc.) and it was able to connect to a PicoProbe. I don't have anything for a CMSIS DAP so you'll need to verify yourself...
Took quite a few tried to get it working under GH actions (plus, RPi's OpenOCD fork doesn't compile cleanly under GCC12!!!) but now I have something I can plug into this toolchain repo and manually fire to get any updates...

Hello Earle,
I can confirm that the above version is working with CMSIS-DAPv2. Many thanks to you for your fast reaction.
If you want to test it with picoprobe, you can use my fork at https://github.com/rgrr/picoprobe/tree/cmsis-dapv2
Thanks for the update! I'll add in the new build process and artifacts to the next pico-quick-toolchain build coming soon.
