I have been debugging this issue. To make sure that I have a clean
environment I am testing the code on Ubuntu 12.4 32bit.  My system was
installed only with "gcov", lcov was not installed. Now I have installed
"lcov" and also I have modified my main cmake file with the below given
code frahment. Instead of modifying CXX_FLAGS, added the profiling related
compiler arguments using the "ADD_DEFINITIONS". In the first case
(modifying CXX_FLAGS) your suggestion "make Experimental" did not work. Now
(ADD_DEFINITIONS) "make Experimental" works without any problem. Can you
comment on why it was not working earlier?

#Code coverage related code

SET (DO_CODE_COVERAGE false CACHE BOOL "Enable Code coverage?")

if(DO_CODE_COVERAGE)
    ADD_DEFINITIONS(-fprofile-arcs -ftest-coverage)
    LINK_LIBRARIES(gcov)
endif(DO_CODE_COVERAGE)

Thanks,
  Lloyd
