qwen3-tts-cpp, omnivoice-cpp, acestep-cpp and vibevoice-cpp shipped
rocm-* variants that silently ran on CPU ([Load] backend: CPU). Two
coupled defects:
- The Makefiles passed -DGGML_HIPBLAS=ON, but the vendored ggml only
understands -DGGML_HIP=ON (GGML_HIPBLAS was removed upstream), so the
ggml-hip backend target was never created and no GPU code was built.
- The CMake foreach that links the ggml GPU backends into the module
listed blas/cuda/metal/vulkan but not hip, so even a built ggml-hip
would not have been linked and its static backend registration would
never run.
CUDA users were unaffected because cublas passes the correct GGML_CUDA=ON
and the foreach already links cuda. Mirror the proven llama-cpp hipblas
block (ROCm clang CC/CXX + AMDGPU_TARGETS) and add hip to each foreach.
Upstream picks the best device via ggml_backend_init_best(), so no
runtime flag is needed once HIP is compiled and linked.
