Agreed. I'm still looking at alternatives for future use that are either
"global stateless" or able to be used via one bundle.

Then I misunderstood you, for me the framework is the framework library.
The launcher is a separate executable, which strictly speaking could be
seen as not part of the framework.
But then we agree :). So I'll add something to the current launcher. I'll
start without an option, though eventually we might need to reconsider that.
A possible (nicer) solution would be to let CMake figure it out. Ie, if
curl is included in any of the build steps, set a flag that is used in some
"define"s in the code enabling/disabling Curl init/destroy.
