Building DigiKam 4.14 with libkgeomanip and other former "extras"

OK.  Thanks for confirming.

I am aware of 5.x betas.  I hesitate to use them right now because of the 
"beta" status.  The announcement post itself [1] says "This version is for 
testing purposes. It’s not currently advised to use it in production."  

Maybe this is overcautious?  Opinions welcome.


If we do stick with the stable branch, we are probably stuck with it until 
next May [2].  So now the question is: for the "former extras" build-deps -- 
how do we co-exist the KDE4 and KF5 versions?   Can the lib packages be made 
co-installable?  Is there a package naming convention? 

From a quick build of libkface 15.04 (KDE4) and 15.12 (KF5) I can see the 
libraries are named differently (libkface.so / libKF5KFace.so).  This gives me 
hope that at least the libs can remain co-installable.  Additionally, the 
includes are in separate sub-dirs of /usr/include so maybe even the -dev 
packages can be co-installable?

Thoughts / advice?

Thanks,
-Steve
