[CMake] Strange behavior with Nightly builds

[Richard Wackerbarth]

I think that you are missing the point of "nightly" runs. The idea behind a nightly run is that each build-bot builds the SAME version of the code.
Just checking out the HEAD for every build would be submitting one "continuous" (perhaps it should be called "head") build. The version built is whatever happens to be the most current head at the time of the build.

So, if you just want "head" builds, don't submit them to two different dashboard areas. Or, if you truly want (and I suggest that it is a good idea) "nightly" builds, either run those builds on a separate bot (source tree) or assure that the continuous builds stop before the end of the logical day and do not resume until after the nightly build has been run.

>> Using one source tree for both continuous and nightly assumes that there will be no continuous runs between the last update incorporated in the nightly run and the time at which the nightly run is performed. It appears that you are not suspending continuous runs between the nightly epoch and the time that you perform the nightly run.
