Does the project rely on anything which is being deprecated/removed?

Also I wouldn't recommend advancing to 3.27 as Debian 11 is on 3.18 and not everyone can upgrade to the latest and greatest.
What we do is to pick the version of what the oldest LTS Ubuntu is using and make that the minimum.

EDIT: Bumped the version to 3.16 which is what Ubuntu LTS is using (https://launchpad.net/ubuntu/focal/+source/cmake). However there are more serious issues as I can't get the Makefile or the CMake version to build the library (#392).

Advancing to 3.27 is probably overkill, I believe VS2022 has 3.26 but I guess 3.16 should do the trick.

Merged and done. Thanks all.
