[CMake] ctest and gcov and cdash

[Leif Walsh]

Hi,

I can't find any documentation that describes gcov integration with ctest in depth, though there seems to be a fair amount of integration with it, as well as with cdash.

As far as I can tell, you're supposed to compile with -fprofile-arcs -ftest-coverage -lgcov and then run all your tests somehow that they generate .gcda and/or .gcno files, which ctest -D ExperimentalCoverage and the like can then pick up, parse, and do something useful with.  My problem is with step 2, running the tests (I think).

I compile with those flags in CMAKE_C_FLAGS and CMAKE_EXE_LINKER_FLAGS and everything seems to go ok.  I then run the tests with ctest.  I don't see any gcov files get generated anywhere, and I don't know what else to try.

Can anyone help, with words or links?
