# Generate a PDB (debug symbols) for ggml-sycl.dll so cdb/WinDbg can resolve
# source lines + frames inside ggml_backend_sycl_init (otherwise the UAF/crash
# in this DLL shows only as a raw offset — no PDB, because icpx under a VS
# generator doesn't emit one by default). /Zi emits debug info during
# compile; /DEBUG at link writes the .pdb beside the .dll. Both are
# config-agnostic so Release builds also carry symbols (the PDB is read by
# cdb from the .dll's side; runtime perf is unaffected). icpx on Windows
# uses the MSVC codegen back-end, so these cdb-loadable PDBs carry line info.
