Compiling android emulator gives grpc missing

Issue

I m trying to build Android s emulator: https://android.googlesource.com/platform/external/qemu.git/+/refs/heads/aosp-emu-30-release

I cloned the entire AOSP source and added some missing packages to the default.xml from repo, here they are:

  <project name="platform/external/qemu" path="external/qemu" revision="791783c6e74c936a8fcd231ad36219385723bb8a" upstream="refs/heads/aosp-emu-30-release" dest-branch="refs/heads/aosp-emu-30-release" groups="pdk" clone-depth="1"/>

I added all of them when I noticed they missing when trying to compile by running android/rebuild.sh on the platform/external/qemu repo. Until I arrived at this error:

CMake Error at android/android-grpc/CMakeLists.txt:2 (add_subdirectory):
  add_subdirectory given source
  "/home/project/disk/aosp/grapheneos-lz_experiments/external/qemu/../grpc/emulator"
  which is not an existing directory.

Solution

There s no platform/external/grpc repo, but there is platform/external/grpc-grpc which as you see below, I made appear at the path external/grpc:

  <project name="platform/external/grpc-grpc" path="external/grpc" revision="0d80ea35ba09d0462ca13f236cc9ddc3fb749c57" upstream="refs/heads/aosp-emu-30-release" dest-branch="refs/heads/aosp-emu-30-release" groups="pdk" clone-depth="1"/>

Would be nice to know why the repo isn t named just grpc instead of grpc-grpc or why the compiler does not try to load from grpc-grpc instead of grpc
