Add a contract test for building the CSE.

To activate the CSE contract test on a given Linux
machine's CMake dashboard, put

CMAKE_CONTRACT_PROJECTS:STRING=cse-snapshot

in the CMake dashboard's initial cache.

The chosen snapshot does not generate subproject
dependency info right now. That code was in a
previous revision in the CSE's svn repo that
apparently has not been merged into the present cse
git repository master branch. After that is fixed up
in the cse repo, we can update the tag here so that
the snapshot built here can run a sub-project based
dashboard script. For now, it runs as one big build
step, building 'all'.
