Kdevelop 5 + kdev-control-flow-graph

Question

I successfully build and installed kdev-control-flow-graph plugin after forking from sandsmark/kdev-control-flow-graph into my own fljx/kdev-control-flow-graph branch with minimal changes.

When I try to enable kdev-control-flow-graph view, though, I receive the error below:

"Unable to create a KGraphViewer instance, please verify that a compatible version is installed."

I am running on Kubuntu 16.04 with KDevelop 5.1.1 and kgraphviewer is installed:

# apt search kgraphviewer
Sorting... Pronto
Full Text Search... Pronto
kgraphviewer/xenial,now 4:2.1.90-0ubuntu2 amd64 [installed]
  GraphViz dot graph viewer

kgraphviewer-dbg/xenial 4:2.1.90-0ubuntu2 amd64
  GraphViz dot graph viewer for KDE 4 debug files

kgraphviewer-dev/xenial,now 4:2.1.90-0ubuntu2 amd64 [installed]
  GraphViz dot graph viewer - devel files

libkgraphviewer2/xenial,now 4:2.1.90-0ubuntu2 amd64 [installed]
  GraphViz dot graph viewer - libs

Then I build KGraphViewer from github and my system now has:

Could anybody please give me any hints on how to make my plugin correctly find KGraphViewer KPart?

Thanks in advance.

KDE dev reporting in.

KGraphViewer is embedded into other applications using KParts framework. Porting KGraphViewer's KPart to Qt5/KF5 is near to release. The bad news is that kdev-control-flow-graph don't work with new KGraphViewer, so this plugin needs to be updated too.
