[Ctk-developers] Changes to the buildsystem for external plug-in support

[Sascha Zelzer]

Good to hear :-)

The example project is a good idea. I already created one for testing 
the changes:

https://github.com/saschazelzer/CTKPluginProject

I could polish it (add some more useful information) and move it to the 
commontk organization.

Thanks,

Sascha
