[CMake] Linking directories on a "sub" CMakeLists

[Xavier Larrode]

Hi Brad and thanks, it seems better.
But now i have this error :
 Error: Attempt to add link library "RelationPosition" to target 
"PieMenu" which is not built by this project.

What's wrong with that ?
should i add the library differently ?
Thanks
