[Docs] ONNX export Optimizer

📚 The doc issue

ONNX export Optimizer https://github.com/open-mmlab/mmdeploy/blob/main/docs/en/experimental/onnx_optimizer.md 我在按照文档记载的办法安装时，报没有CMakeLists.txt的错误

1.执行的命令 export Torch_DIR=$(python -c "import torch;print(torch.utils.cmake_prefix_path + '/Torch')") cd $Torch_DIR cmake -DTorch_DIR=${Torch_DIR} -DMMDEPLOY_TARGET_BACKENDS="onnxruntime;torchscript"

2.环境 Torch_DIR指向 miniconda3/envs/openmmlab/lib/python3.8/site-packages/torch/share/cmake/Torch

这个目录下只有 TorchConfig.cmake TorchConfigVersion.cmake 这2个文件

3.问题 报没有CMakeLists.txt的错误

请问我怎么才能解决这个问题？执行命令的当前目录应该是哪里？ 我的mmdeploy是用 pip install mmdeploy==1.3.1 安装的
