CMake Linux Hack

Beginning with its most recent version (3.25 at the time of writing this post), CMake provides the LINUX variable, which I used in my previous post. Of course, developers on Linux tend to use the version of CMake they can install from their distribution’s package manager. On Ubuntu 22.04 LTS that would be 3.22, and even on the most recent Ubuntu version (22.10) we’re at 3.24 — meaning this variable is not available in these CMake versions.
