[CMake] Using gcov/lcov and valgrind with cmake

[Gerhard Gappmeier]

Hi David and Cole,

I don't understand how it should help to add this to CMakeCache.txt.
This file is only temp file and is not checked in the repo.
Can the MEMORY_CHECK options also be set in the CMakeLists.txt?

I have the coverage test working at the moment using this construct in
the CMakeLists.txt:
# enable coverage analysis using GCC and GCOV
IF (CMAKE_COMPILER_IS_GNUCC)
    SET(CMAKE_C_FLAGS "-g -O0 -Wall -fprofile-arcs -ftest-coverage")
    SET(CMAKE_CXX_FLAGS "-g -O0 -Wall -fprofile-arcs -ftest-coverage")
    SET(CMAKE_EXE_LINKER_FLAGS "${CMAKE_EXE_LINKER_FLAGS} -fprofile-arcs
-ftest-coverage -lgcov")
ENDIF()
It works, but I'm not sure if this is the right Cmake way to do that.

You can checkout the complete example using
git clone git://github.com/gergap/helloworld.git

Any help is appreciated to complete this helloworld cmake tutorial.
