[CMake] CTest and CDash for CI

[Andrea Galeazzi]

I'm currently evaluating a good tool to introduce a continuous 
integration model in my workflow. Because I use CMake to manage all my 
projects, I'd like to also use CTest/CDash in order to accomplish such 
task. I start to read something about it but I didn't find the right 
answers to some questions:
1 - Can I define a test only to know if the project compiles without any 
errors?
2 - Can I update a project from sourcesafe automatically?
3 - Can an email be forwarded to only people who performed a check-in 
from the previous successful build?
Thanks
