Done and merged into next, including a test.
When merging, please have a look at:
f5e46ef -don't pull in CheckTypeSize.cmake from the cmake which is being built

IMO it should be fine.
cmcurl/CMakeLists.txt pulled the CheckTypeSize.cmake from the cmake which is 
being built into the cmake which is building. This broke with cmake 2.6.4, 
since CMakeExpandImportedTargets.cmake now uses a feature from cmake 2.8.3 
(CMAKE_CURRENT_LIST_DIR)
