Previously coverage data was parsed by CTest (generating Coverage.xml and CoverageLog.xml) and then uploaded to CDash. With this new approach we now upload the .gcov files directly to CDash and parse them server-side instead.

Knowing it's only supposed to work with ctest_coverage_collect_gcov()
I will look further tomorrow. Thanks.

But does this mean ctest_coverage() is deprecated and
ctest_coverage_collect_gcov() is a strict superset? While reading the
docs I got the impression ctest_coverage() is *the* way, with
ctest_coverage_collect_gcov() something you notice while reading about
something else, not too clear why it does exist.
