Exporting LD_LIBRARY_PATH for interfaces about ament_cmake HOT 5 CLOSED

If a package only exports dependencies but doesn't have any libraries why would it need to set the LD_LIBRARY_PATH? The assumption is that the dependency has defined the LD_LIBRARY_PATH itself.

I think there was a slight typo in @stonier initial comment. We were interested in whether LD_LIBRARY_PATH should get set when ament_export_interfaces(...) is called. We're not sure how ament_export_interfaces(...) and ament_export_libraries(...) are supposed to interact (if at all).

Yes, indeed. Thanks @clalancette. Intended ament_export_interfaces and fixed appropriately in the description above.

The problem should be fixed in #135. @stonier It would be great if you could confirm that it addresses your use case.

@stonier I updated the patch in the referenced PR. You will have to change your code to actually pass the export name instead of the target as well as pass the new option added in the referenced PR. Please let me know if that works for your use case.
