So with this:

  LogicalResult matchAndRewrite(linalg::MatmulOp op,
                                PatternRewriter &rewriter) const override {
    rewriter.replaceOpWithNewOp<meh::MatmulOp>(op, op.getOperand(0),
                                               op.getOperand(1));
    return success();
  }

I get this build error:

Here is my .td:

def Meh_MatmulOp : Meh_OP<"matmul", [
  ]> {
  let arguments = (ins 
    AnyTensor:$lhs, 
    AnyTensor:$rhs
  );
  let results = (outs
    AnyTensor:$dst
  );
}
