chore: update minimum cmake version to 3.22 (#1812)

AustinBenoit · web-flow · commit 7652ad7aa7c4 · 2026-02-23T15:30:21.000Z
* chore: update minimum cmake version to 3.30

* Chore: update to 3.22

3.30 was causing issues with the Android builds so it makes more sense to start
with a 3.22 upgrade and then try for 4.X upgrade later. We will still get most
of pros when doing this upgrade anyways.

* fixup: the change now requires a cxx label so its included

* Fix up the project name changed an removed comments

* Make project name consistent
