[CMake] debug git fetch

[Tom Deblauwe]

Hello,

In Ctest: How can I get the loggings of the git fetch command? I keep 
getting that "/usr/bin/git" "fetch" has failed when doing an update. So 
I see in the ctest source code that there is some extra logging for git, 
but using "-VV --debug" as extra params for the ctest call is not 
producing the git loggings. How can I get them?

Thanks,
Best regards,
Tom,
