I basically have the same project structure as you describe. I am also not sure what the best practice is here, but this is what I currently do: I set all dependencies where they are required: right in the local CMakeLists.txt, i.e. sub_dir-1/CMakeLists.txt. Then "export" all required include/define/compiler flags dependencies via INTERFACE or PUBLIC flags of the various target_*** cmake functions, as appropriate. The sub-projects are added via add_subdirectory in cmake. This way I can build each CMakeLists.txt individually if needed but still have everything DRYish.
