I am trying to use CodeCoverage and failing

I am having the following error...
make Unit_Tests_coverage
[ 90%] Built target Unit_Tests
[100%] Resetting code coverage counters to zero.
Processing code coverage counters and generating report.

I can tell the gcda files are not being created....but they have SOMETIMES been created but mostly I get this error. Is this a bug? Or a screw up on my part? Have mercy on my poor CMakeTest file I am just now learning cmake.
I think you are missing SET(CMAKE_CXX_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage") (it is described in the usage documentation).
You need the following:
include(CodeCoverage)
APPEND_COVERAGE_COMPILER_FLAGS()
SETUP_TARGET_FOR_COVERAGE(NAME "somename" EXECUTABLE "someexec")
