ci(windows-cuda): pass /bigobj to fix C1128 build failure#15
Merged
Conversation
stable-diffusion.cpp's Windows CUDA build fails with: fatal error C1128: number of sections exceeded object file format limit: compile with /bigobj src/stable-diffusion.cpp combined with the CUDA backend's generated code exceeds MSVC's default COFF section limit per object file. The windows-latest-cmake job already works around the same class of issue with -DCMAKE_CXX_FLAGS='/bigobj'; apply the same flag to the CUDA build.

LGTM. This is a focused fix for the MSVC C1128 section-limit failure in the Windows CUDA build, and the affected windows-latest-cuda (sm_89) PR job now passes.
