The matrix value cuda_ldpath: "cuda-12.9" expands to /usr/local/cuda-12.9 in LD_LIBRARY_PATH, but CUDA shared libraries are typically under a lib directory (e.g., targets/aarch64-linux/lib / lib64) rather than the toolkit root. If this variable is meant to make runtime linking work, it should point at the directory that actually contains the .so files.

cuda_ldpath values point at CUDA install roots (e.g. /usr/local/cuda-12.9 and /usr/local/cuda-13.2/compat_orin). LD_LIBRARY_PATH needs directories that directly contain the shared libraries (commonly .../lib64 or .../targets/aarch64-linux/lib, and for the compatibility package likely a .../lib subdir). As-is, the dynamic loader won’t search subdirectories, so runtime/test steps may fail to locate CUDA libs. Consider changing cuda_ldpath to the actual library directory paths for each toolkit/compat combo.

Setting LD_LIBRARY_PATH as "/usr/local/...:$LD_LIBRARY_PATH" can leave a trailing ':' when LD_LIBRARY_PATH is empty/unset, which causes the dynamic linker to also search the current working directory. Please adjust the append logic so an empty LD_LIBRARY_PATH does not introduce an empty path element (for safety and determinism).

echo "LD_LIBRARY_PATH=/usr/local/${{matrix.cuda_ldpath}}${LD_LIBRARY_PATH:+:$LD_LIBRARY_PATH}" >> "$GITHUB_ENV"
