missing Python.h on system where it is present

[ekg]

I'm unable to build this using cmake.

/home/erik/libbdsg/bin/_deps/pybind11-src/include/pybind11/detail/common.h:112:10: fatal error: Python.h: No such file or directory

However, I am able to build odgi, which includes pybind11 bindings and depends on Python.h.

What are the dependencies for libbdsg?

I think it just needs OpenMP, Python 3, and Doxygen for making the docs.

I revised how we find Python in early May; if you have a different default version of Python 3 than the latest Python 3 you have headers available for, you can get into trouble, and the CMake file now tries to prevent this by forcing you to explicitly pick a consistent Python version in such cases.
