"enabled libtorch" is already in the file, why we need to add a new line here.


> torch/torch.h "torch::Tensor" -ltorch -lc10 -ltorch_cpu -lstdc++ -lpthread
> +enabled libtorch_cuda && enable libtorch && check_cxxflags -std=c++17

Please align the spaces between " enabled libtorch_cuda" and "&&" with others already in the file.
