[CMake] Looking for documentation on coverage analysis with cmake

[Thorben Kröger]

Hi,
I've googled for quite a long time and looked into the CMake book, but I 
cannot find some good information about CTest's make ExperimentalCoverage 
target. At this stage, I have everything set up, but I need some help 
interpreting the output.

I want to do coverage analysis of a library we wrote. I specifically need to 
tell cmake that some third party libraries we use should _not_ be considered 
when calculating percentages.

I also wonder if there is a way to generate some nice html pages locally that 
show the coverage for each source file, like it seems possible with cdash (We 
don't have a dashboard unfortunately) or lcov.

Thanks for any tips,

Thorben
