Oops... Somehow I was under the impressioon QCA2 was already a required 
package.

Compiling without Remote Widgets suppor is not yet possible at the moment, but 
I can make sure it won't be required. All QCA related code is only in one 
class: Credentials. I can add some cmake stuff and ifdefs to make sure 
validSignature() always returns false and canSign always returns false in case 
of a missing QCA. This makes sure accessRemoteApplet and publish() always just 
plain fails. I should probably return no remoteApplets in AccessManager as 
well so we don't list zeroconf announced plasmoids in places that do that 
(soon the new widget explorer for example), since you won't be able to connect 
anyways without QCA.
I'm now dealing with some personal stuff, but I'm sure I'll have the time 
tomorrow to fix this, and make QCA2 an optional dependency for libplasma.
