Why you add CMakeLists.txt file on tools directory, not in new directory under tools for onnx-subgraph? (ex. tools/onnx-subgraph/CMakeLists.txt)

And your commit does not have any comment body. Please add body with signing.

@chenyx113 , you are closing and add new PRs for some time.
I hope you can update commits, not closing.
Is there any problem with that?

ok, I will update based previous commit from now on.
no other problems, when I updating, I found current commits is behind master branch already, and rebase will introduce updating records in current PR, just want to have a clean screen for reviewing.

thanks for suggestion, I will follow it in future
