pybind11 does not contain a CMakeLists.txt file.

If you have the error pybind11 does not contain a CMakeLists.txt file when building with python wrapper on, just update the pybind11 submodule:

git submodule update --init --recursive

It would be helpful to add this to the install/build instructions.

I use git clone --recurse-submodules https://github.com/pybind/pybind11.git in the spconv1.0-master/third_party directory
