Problem description & steps to reproduce

I'm running into this on Clang 22.1.4 and CMake 3.31.6 on Ubuntu 25.04 for what it's worth.

llama_build_info is an "undeclared identifier", despite being linked through llama-common-base via llama-common. I believe this broke in 6990e2f.

I generated the cmake build as follows:

cmake -G Ninja .. \
 -DCMAKE_BUILD_TYPE=Release \
 -DCMAKE_CXX_COMPILER=clang++ \
 -DCMAKE_C_COMPILER=clang \
 -DCMAKE_CUDA_HOST_COMPILER=g++-15 \
 -DCMAKE_INTERPROCEDURAL_OPTIMIZATION=ON \
 -DCMAKE_LINKER_TYPE=LLD \
 -DGGML_CUDA=On \
 -DGGML_CCACHE=OFF

For me the issue was that I had an extra build-info.h file in the repo root from some old build. 6990e2f adds a few "build-info.h" includes that picked up the old header instead of the real common/build-info.h one. Deleting the old one solved it
