dundargoc 7840760776 build: bump minimum cmake version to 3.13
The benefits are primarily being able to use FetchContent, which allows
for a more flexible dependency handling. Other various quality-of-life
features such as `-B` and `-S` flags are also included.

This also removes broken `--version` generation as it does not work for
version 3.10 and 3.11 due to the `JOIN` generator expression.
