I'm trying to install face-recognition on ubuntu but dlib keeps failing to build. I tried running python3 setup.py install but it returned some error about boost. After installing boost it still can't locate it.

1. how can I specify the paths for boost(for /path/to/dir/boost_1_78_0 and /path/to/dir/boost_1_78_0/stage/lib) An online source suggested that I append it to the CMakeLists.txt but there are two files with that name in the dlib-19.6 folder.ie. /path-to-dir/dlib19.6 has CMakeLists.txt and /path-to-dir/dlib19.6/dlib also has CMakeLists.txt. which one is the right one?

2. how can I solve the issue below:

   /tmp/pip-install-md97yl8n/dlib_c8973decd1e045cb9182990e2e1f228e/dlib/external/pybind11/include/pybind11/detail/common.h:112:10: fatal error: Python.h: No such file or directory 112 | #include <Python.h> | ^~~~~~~~~~ compilation terminated.

which is part of the error message output by the terminal when I run pip install face-recognition

3. is there any way that I could automatically install dlib and boost and have the system automatically specify the necessary paths?
