Message:

Merged resource2 branch back to trunk.

IMPORTANT NOTE:
Upon this merge you need to specifically call your data directory "data_extern" when checking it out (when you don't provide a name, it will be just called 'trunk').
The new CMake variable is EXTERNAL_DATA_DIRECTORY. DATA_DIRECTORY now points to the one the source part of the repository.
UPDATE YOUR DATA DIRECTORY AS WELL!!!
