Hi,

I have a setup for doing something that you might be looking for. In the
top-level CMakeLists.txt[1], I add some options to build with coverage.
I also have a couple of macros[2] which make generating testing targets
much nicer[3].

These macros do not assume CTest is enabled nor conflict with it. AFAIK
they are gcov-specific, but another option could be added to use lcov
instead. Similar with valgrind.

If you have any questions or suggestions, feel free to ask.
