[CMake] CDash submissions show up as two entries, one row for update, one for build/test etc

Uh-oh. That sounds familiar. The same thing happened to me once. And if you don't set CTEST_SITE you get one entry per step (i.e. update, configure, build, test). IMHO CTest should do a) abort with a clear error message if CTEST_SITE is not a valid hostname for any reason (i.e. spaces or newlines) and b) set it to the hostname of the machine if it is not set at all.

Any opinions on this before I file a bug report?
