Hello! With native, I get

cmake -B lenux \

  -DGGML_BLAS=OFF \
  -DGGML_RPC=ON \
  -DGGML_MAX_CONTEXTS=2048 \
  -DGGML_SCHED_MAX_COPIES=1 \

With -DCMAKE_CUDA_ARCHITECTURES="86;89;120", I get the same error:

I edited it like this

@Panchovix not sure why there's an '^' at the end of if statement, copy-paste error?

@am17an oof my bad!

Now with the corrected regex, I can build with either native (not setting a CUDA arch), DCMAKE_CUDA_ARCHITECTURES native and DCMAKE_CUDA_ARCHITECTURES 86;89;120.

I assume either of these 3 will include mxfp4 support?
