[CDash] Branch Coverage with GCov

[Cristian Morales Vega]

Hi,

I have tried to reproduce
https://blog.kitware.com/additional-coverage-features-in-cdash/ but I
have had no luck.

The gcov.tar file is being created. I guess uploaded, but it's not
100% clear from the ctest output. In CDash I can't see coverage
information at all. And I'm wondering why the script uses
ctest_coverage_collect_gcov() instead of ctest_coverage().

Before trying to reproduce with branch_coverage_example.tar.gz I was
trying to do it in my project by using ctest_coverage and basically
just trying to add -b or -c to CTEST_COVERAGE_EXTRA_FLAGS. There I got
the coverage info, as always... but with no extra branch information I
could see.

Regression? There is something obvious I can't see?
