ctest_coverage -------------- Perform the :ref:`CTest Coverage Step` as a :ref:`Dashboard Client`. :: ctest_coverage([BUILD <build-dir>] [APPEND] [LABELS <label>...] [RETURN_VALUE <result-var>] [CAPTURE_CMAKE_ERROR <result-var>] [QUIET] ) Collect coverage tool results and stores them in ``Coverage.xml`` for submission with the :command:`ctest_submit` command. The options are: ``BUILD <build-dir>`` Specify the top-level build directory. If not given, the :variable:`CTEST_BINARY_DIRECTORY` variable is used. ``APPEND`` Mark ``Coverage.xml`` for append to results previously submitted to a dashboard server since the last :command:`ctest_start` call. Append semantics are defined by the dashboard server in use. This does *not* cause results to be appended to a ``.xml`` file produced by a previous call to this command. ``LABELS`` Filter the coverage report to include only source files labeled with at least one of the labels specified. ``RETURN_VALUE <result-var>`` Store in the ``<result-var>`` variable ``0`` if coverage tools ran without error and non-zero otherwise. ``CAPTURE_CMAKE_ERROR <result-var>`` Store in the ``<result-var>`` variable -1 if there are any errors running the command and prevent ctest from returning non-zero if an error occurs. ``QUIET`` Suppress any CTest-specific non-error output that would have been printed to the console otherwise. The summary indicating how many lines of code were covered is unaffected by this option.
