Build instructions for the prebuilt QEMU with rutabaga/gfxstream support ?

The instructions on [crsovm doc](https://crosvm.dev/book/appendix/rutabaga_gfx.html) seems kinda outdated.

I am having linking issues during the final stage when building QEMU :
```
/usr/bin/ld: /data_ssd_2t/ruinland_aosp/cuttlefish/qemu_rutabaga/build/deps/prefix/lib/librutabaga_gfx_ffi.so: undefined reference to `gfxstream::vk::EmulatedPhysicalDeviceMemoryProperties::tr
ansformToGuestMemoryRequirements(VkMemoryRequirements*) const'
/usr/bin/ld: /data_ssd_2t/ruinland_aosp/cuttlefish/qemu_rutabaga/build/deps/prefix/lib/librutabaga_gfx_ffi.so: undefined reference to `gfxstream::vk::EmulatedPhysicalDeviceMemoryProperties::Em
ulatedPhysicalDeviceMemoryProperties(VkPhysicalDeviceMemoryProperties const&, unsigned int, gfxstream::host::FeatureSet const&)'
/usr/bin/ld: /data_ssd_2t/ruinland_aosp/cuttlefish/qemu_rutabaga/build/deps/prefix/lib/librutabaga_gfx_ffi.so: undefined reference to `gfxstream::vk::EmulatedPhysicalDeviceMemoryProperties::ge
tHostMemoryInfoFromGuestMemoryTypeIndex(unsigned int) const'
```

I doubly checked with `libgfxstream_backend.a`, the symbols are indeed undefined :
```
0000000000000000 W gfxstream::vk::EmulatedPhysicalDeviceMemoryProperties::getGuestMemoryProperties() const
U gfxstream::vk::EmulatedPhysicalDeviceMemoryProperties::transformToGuestMemoryRequirements(VkMemoryRequirements*) const
U gfxstream::vk::EmulatedPhysicalDeviceMemoryProperties::getHostMemoryInfoFromGuestMemoryTypeIndex(unsigned int) const
...
0000000000009f58 T gfxstream::vk::importExtMemoryHandleToVkColorBuffer(unsigned int, unsigned int, int)
U gfxstream::vk::EmulatedPhysicalDeviceMemoryProperties::EmulatedPhysicalDeviceMemoryProperties(VkPhysicalDeviceMemoryProperties const&, unsigned int, gfxstream::host::Feature
Set const&)
```

And these methods are supposedly to be part of gfxstream.

Is there a write up of details (including proper commit hashes) for building the QEMU with rubataga/gfxstream ?
I tried the ones from :
https://linaro.atlassian.net/wiki/spaces/ORKO/pages/28985622530/Building+QEMU+with+virtio-gpu+and+rutabaga+gfx
Yet the commit hashes are quite old and fail to build.
