Mettre a jour l'analyse de couverture de code.

L'analyse de la couverture de code a été supprimé lors du nettoyage du @CMakelist.txt@ et du @README.md@ dans l'issue #5539.

1. 1. 1. 1. -DTEST_COVERAGE

Tests can output line coverage statistics if you define `TEST_COVERAGE` :

cmake .. -DBUILD_SHARED_LIBS=ON -DBUILD_TESTS=ON -DTEST_COVERAGE=ON

Run tests with :

make test

Create coverage reports with :

GCOV_PREFIX=$HOME/src/cpf-redshift/RedshiftLibrary/ GCOV_PREFIX_STRIP=4 lcov -q -c -t "result" -o tests.cov --no-external -b $HOME/src/cpf-redshift/RedshiftLibrary/ -d CMakeFiles
lcov -q -r tests.cov '/tests/src/' -o coverage.info
genhtml -o coverage coverage.info
</pre>

IF(TEST_COVERAGE)
SET(GCC_COVERAGE_COMPILE_FLAGS "--coverage")
SET(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} ${GCC_COVERAGE_COMPILE_FLAGS}")
SET(cpf-redshift_COVERAGE "True")
ELSE()
SET(cpf-redshift_COVERAGE "False")
ENDIF()
