[CMake] Using gcov/lcov and valgrind with cmake

[Bill Lorensen]

It should be done in the CMakeCache.txt file. In most projects, with
multiple developers and multiple platforms, you would not want to
perform coverage on every build. Look at VTK:
http://www.cdash.org/CDash/index.php?project=VTK or ITK:
http://www.cdash.org/CDash/index.php?project=Insight
These toolkits try to build on many different platforms with many
different combinations of builds (debug, release, coverage,
valgrind...).

I suppose, if you have a small development community, with a small
number of supported platforms, then including in the CMakeLists.txt is
an option. But that means you cannot build an efficient release build.
Still, I would recommend doing this in the CMakeCache.txt (which can
be done with a ctest script).
