OS conditional compilation
If you need to compile code based on which distribution of Operating System you are running, you can use predefined "VV_OSNAME_ID" constant, with the following values:
Examples
Compile guarded code if running Ubuntu 22 only:
// Compile only for Ubuntu 22
#if VV_OSNAME_ID==1
    ...
    @This is Ubuntu 22 only.
    ...
#endif

Note that generally the last 2 releases for a given distribution are available at any given moment, and the above list represents historical list of OS distributions that are (or were) available.
