[CMake] How are modules tested?

[Robert Ramey]

I've been having difficulties creating an Xcode project.  In the course 
of this work, I've had occasion to investigate the FindBoost.cmake file. 
Looking at it - I don't see how it can possible work.  On my system 
libraries are created libboost_<module>_<compiler>_abi.a and I don't see 
anything similar to this.  Are there any test results I can look at to 
verify that this actually works?
