Error while trying to install odoo15 requirements.txt on M1

Question

I am trying to install the requirements for odoo15 on my MBP M1 Pro running MacOS Ventura 13.0 in my virtual environment running python 3.10.8

but I keep getting the following error:

build/temp.macosx-12-arm64-cpython-310/_openssl.c:575:10: fatal error: 'openssl/opensslv.h' file not found
      #include <openssl/opensslv.h>
               ^~~~~~~~~~~~~~~~~~~~
      1 error generated.
      error: command '/usr/bin/clang' failed with exit code 1
      [end of output]

  note: This error originates from a subprocess, and is likely not a problem with pip.

Now, I have already spent a lot of time researching and it seems that openssl might be the problem here

I have already install openssl via brew, it is running the newest version, as suggested in this GitHub issue

I have installed the newest version of pip as suggested in this StackOverflow post

Edit: I have now also tried setting these flags as suggested in this StackOverflow post:

export LDFLAGS="-L/opt/homebrew/opt/openssl@1.1/lib"
export CPPFLAGS="-I/opt/homebrew/opt/openssl@1.1/include"

I have also retried everything in another venv using Python version 3.8
