[CMake] CTest: Cannot find any coverage files. Ignoring Coverage request.

[emeplease]

Thank you David, my issue is solved.
It's because the SET( CMAKE_CXX_FLAGS ) inside CTest script has no effect ,
instead, I need to insert lines into

    SET (CTEST_INITIAL_CACHE "
    ...
    )


Also, I mistakenly override the CMAKE_CXX_FLAGS in the root CMakeList.txt


Regards,
Joseph
