Upstream projects:

• https://github.com/martinmoene/any-lite
• https://github.com/martinmoene/byte-lite
• https://github.com/martinmoene/expected-lite
• https://github.com/martinmoene/observer-ptr-lite
• https://github.com/martinmoene/optional-lite
• https://github.com/martinmoene/span-lite
• https://github.com/martinmoene/status-value-lite
• https://github.com/martinmoene/string-view-lite

These are individual future compatability headers for C++.

Having a nonstd-<header>-lite wrap would be really useful for these projects.

It seems every package is named like

set( unit_name       "any" )
set( package_name    "${unit_name}-lite" )

Each individual name looks unique enough so I am happy to create
