The RunCMake.TargetPropertyGeneratorExpressions failure was probably a side-
effect of the incremental builds of the Continuous configuration. 

Still, some of the platforms fail the test, and don't give any information 
about why:

Can someone please provide more information (backtrace or further 
investigation) for one of the failing platforms?
