Dependency to Network Manager / kf5-NetworkManagerQt in plasma-workspace

[Bernd Steinhauser]

Hi,

since the commit with the id 78c97fin plasma-workspace [1], it depends on 
NetworkManagerQt and hence on Network Manager unconditionally. The use case 
outlined in the commit is that the data engine tries to access wlan via network 
manager to find out which hotspots are around and use that to get location 
informations.
Now apart from the fact that I wouldn't want it to do that and that it couldn't 
do it on my system, because it uses systemd-networkd for network configuration, 
this results in a dependency on Network Manager.
I do understand that Martin when introducing this commit thought that most 
systems running Plasma 5 will run Network Manager anyway, since that is a 
preferred way of setting up network for many distributions. However, there are 
many systems, that don't need and use Network Manager and possible don't want to 
have it installed at all.
Aside from my desktop computer, examples could for example include workstations 
at universities, which often have a static network setup (doesn't matter how 
that is setup).

So the question is:
Could you make this feature, and therefore the dependency on Network Manager, 
optional at build time?

Currently, I just comment out the geolocation dataengine in the corresponding 
CMakeLists.txt and remove the dependency when building plasma-workspace, but 
since I don't know about the code, I can't judge if this has any unforeseen 
consequences, if a data engine is missing.

Best Regards,
Bernd
