[CMake] CTest w/ Coverage

[Daniel Stonier]

Ian, are you using ccache?

Just found that buggers the process up completely. If you're using a
ccache link to the compiler, then the two-step compile-link process
fails to build the gcno coverage file (or misplaces it). I removed my
ccache links and did it again manually and presto, the coverage file
appeared.

Then went back to cmake, didn't change any of the files I listed in
the earlier email, no CTestConfig.cmake etc etc and it worked fine.

I'm not sure if there's a fix for getting it to work with ccache or
not, will keep digging around.

Cheers,
Daniel Stonier.
