Describe the bug

https://github.com/open-mmlab/mmdeploy/blob/master/docs/zh_cn/01-how-to-build/build_from_script.md

I install the mmdeploy in the ubuntu-20.04, and by the way of above one, however, the result shows that the ncnn’s ops_is_available is false.

what’s more, in the progress of my install, there are some red lines in the dos window: ----------build and install mmdeploy---------- fatal: not a git repository (or any parent up to mount point /) Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set). fatal: not a git repository (or any parent up to mount point /) Stopping at filesystem boundary (GIT_DISCOVERY_ACROSS_FILESYSTEM not set). – CMAKE_INSTALL_PREFIX: /home/jdskddd/mmdeploy/build/install – Build ncnn custom ops – ncnn library found! **CMake Error at csrc/mmdeploy/backend_ops/ncnn/pyncnn_ext/CMakeLists.txt:7 (add_subdirectory): The source directory

/home/jdskddd/mmdeploy/third_party/pybind11

does not contain a CMakeLists.txt file.

CMake Error at csrc/mmdeploy/backend_ops/ncnn/pyncnn_ext/CMakeLists.txt:10 (pybind11_add_module): Unknown CMake command “pybind11_add_module”.**

Reproduction

$ cd mmdeploy $ python3 tools/scripts/build_ubuntu_x64_ncnn.py $(nproc)
