abseil-cpp Missing CMakeLists.txt (arm64)

[knuxyl]

I am building this on an arm64 board, Radxa Rock 5B, and the configure step is failing because it cannot find abseil-cpp. I only found one reference to this in aurora's cmakelist.txt, which said it was inside extern/aurora/extern/dawn/thirdparty, but that directory doesn't exist.
I cloned this correctly, recursively, and updated submodules and all that. I even ran the normalize_submodules.sh script just in case but that didn't pull it in. I'm currently cloning dawn into that directory but I think the intention here is to not pull the whole dawn project and only use parts of it? If so, it's broken on arm64 gentoo linux because it's not pulling it in. I'm using clang20 or gcc 15 and cmake 4.1.2.

I'm pulling in dawn right now but it might take a while. But this isn't the first time I have come across this problem trying to build this.

Edit: So this isn't the issue. I cloned almost the entire dawn repo until it started asking for credentials and verified abseil-cpp was there and had a cmake file. I tried to rebuild and got the same error.

-- Dawn: using Abseil at /mnt/256GB/source/src/AxioDL.metaforce/build/_deps/dawn-src/third_party/abseil-cpp
CMake Error at build/_deps/dawn-src/CMakeLists.txt:461 (add_subdirectory):
The source directory

/mnt/256GB/source/src/AxioDL.metaforce/build/_deps/dawn-src/third_party/abseil-cpp

does not contain a CMakeLists.txt file.

I'm building following the instructions, and have tried other ways as well. Always same problem.
I do have abseil-cpp libraries installed on the system, maybe an option for system libraries? I think system libraries should be preferred for everything unless otherwise stated with like env variables. I don't know, including all this google code is probably a nightmare.

Edit again:
Potential solution
Clone the project abseil-cpp at https://github.com/abseil/abseil-cpp in the /extern directory
edit /extern/CMakeLists.txt, add this line above add_subdirectory(aurora)
add_subdirectory(abseil-cpp)
now project is building.

Edit:
metaforce built but i get a No rule to make target 'hecl'.
I run metaforce and it loads, but after selecting an iso, it aborts. This could be the vulkan driver for this GPU, but there's some other problems listed that might be worth fixing.
