I see you found the solution, indeed you should edit the paths in CastleEngineManifest.xml to point Castle Game Engine build tool to where your Indy sources are.

Note that we have

Edit the client/CastleEngineManifest.xml and server/CastleEngineManifest.xml files and replace the your/path/to/Indy10 example there with actual path to Indy units on your system. It can be an absolute path (like c:/indy/ or /home/me/indy) or relative path (like ../../indy/).
