 In NetBSD you will almost certainly need to have a newer compiler installed.

 In FreeBSD similarly, you might want to install a different compiler.
+You will also, as in NetBSD, need to install cmake, boost and ragel packages.
 Using the example of gcc12 from pkg:

 and then before beginning the cmake and build process, set
