Perhaps name the phase 'use-system-enet-package' or
'unbundle-enet-moonlight'.

It seems their build system is broken if it doesn't install these, and
thus should be reported upstream (with a comment linking to it here).

Please sort inputs :-).

I'd use "GameStream protocol core implementation"

Provides the "core".

The license should be gpl3+, as the LICENSE text contains the original
"or any later version" and there doesn't seem to be source headers
contradicting that.
