[CMake] CTest w/ Coverage

[alex gouaillard]

if you using gcc, compile you code with the right options, and you re  
good.
http://www.cmake.org/Wiki/CTest:Coverage
Coverage With C++

Currently coverage is only supported on gcc compiler. To perform  
coverage test, make sure that your code is built with debug symbols,  
without optimization, and with special flags. These flags are:
-fprofile-arcs -ftest-coverage
Also make sure to pass these flags to C compiler, CXX compiler, and  
the linker. For example:
CXXFLAGS="-g -O0 -Wall -W -Wshadow -Wunused-variable \
  -Wunused-parameter -Wunused-function -Wunused -Wno-system-headers \
  -Wno-deprecated -Woverloaded-virtual -Wwrite-strings -fprofile-arcs - 
ftest-coverage"
CFLAGS="-g -O0 -Wall -W -fprofile-arcs -ftest-coverage"
LDFLAGS="-fprofile-arcs -ftest-coverage"
"
"

then just run ctest.

no need for special ctest script.
