Old version of Pybind11 find the wrong python version

[jamesETsmith]

Problem

Hello! I just wanted to give you all a heads up that you might want to update the pybind11 that's packaged with taco. The version of pybind11 you've included has some problems when they search for python and can sometimes target the wrong python version (which happened to me when I tried to make the python bindings for taco). You can check out this pybind11 issue (pybind/pybind11/issues/1090) and PR (pybind/pybind11/pull/2370) for more details.

Version Info

• Taco: 1114197
• CC/CXX: gcc 10.2
• Python 3.9.1

Solution

Updating to the latest version of pybind11 fixed this for me.

Happy to make a PR for this if that'd be helpful.

PyBind should actually be a git sub-module. PR #400 will address this and will be removed from draft once I figure out why one of the unit tests fail.

Edit: I have removed the PR from draft so now pybind11 will hopefully be a git submodule if there are no objections. I currently use v2.6 which seems like the latest stable release. It should be easier for us to update pybind in the future now as well :)
