[Ctk-developers] CTK-Plugins Cycle dependencing detected

[Sascha Zelzer]

Hi Sergio,

inter-plugin dependencies are stated in the "manifest_headers.cmake" 
file in the plug-in folder, using the "Require-Plugin" header. If this 
file exists in your plug-in (it is optional), please check its contents.

Your CMake code below looks correct.
