Hi @simbit18 , I am using CMake (but I have also used Make and it works
too). Here is the output of the entire CMake build process on my machine:

So I don't receive this warning locally.

I went with this method because the compiler will automatically fail in
places
where an undefined symbol is used, and that prevents me having to add a
bunch of
`static_assert` calls. However, if this can't be resolved with the build
system
(and it looks like it can't), I'll revert back to using `-1` as the default
value and adding static assert statements.
