# Build tts_pipeline contre chraac-llama au lieu de ql/ggml (qualcomm fork).
# Cible : exploiter le ggml-cpu chraac qui a démontré RTF 0.96 sur decoder seul
# (vs 1.47 llama-upstream, cf /opt/Kazeia/kazeia-tts-perf-validated/).
#
# Diff vs build_tts_pipeline.sh :
#  - headers depuis /opt/Kazeia/chraac-llama/{include,ggml/include}
#  - link libs depuis dist/lib-chraac (copies de /opt/Kazeia/chraac-llama/build-android-kazeia/bin)
#  - libqwen3tts-decoder.a depuis /opt/Kazeia/kazeia-tts-perf-validated (build chraac validé)
