[CDash] GitHub Status API support

[David Cole]

Surely there's a way to query for the build id given the components
that go into making up the unique key (build stamp, build type, site,
.... I can't remember all the components required to get the unique
key....?)

Is there a way to send that up to CDash and get a build id response
back? (Because those things should be well-known by the dashboard
submitter.)

CDash includes this buildid in its XML response It looks like the only way to see this from the command-line currently is to call ctest with the --debug argument. Here's an example:

The concept here is that CDash can get busy at certain times of day. So instead of asking the testing clients to wait while CDash parses their XML files, the submissions get added to a queue that CDash works on offline. So just because your build has completed in Jenkins doesn't mean that CDash has parsed its results yet.
