      #

      # 2012-01-31, Lars Bilke

      # - Enable Code Coverage

      #

      # 2013-09-17, Joakim Söderberg

      # - Added support for Clang.

      # - Some additional usage instructions.

      #

      # 2016-02-03, Lars Bilke

      # - Refactored functions to use named parameters

      #

      # 2017-06-02, Lars Bilke

      # - Merged with modified version from github.com/ufz/ogs

      #

      #

      # USAGE:

      #

      # 1. Copy this file into your cmake modules path.

      #

      # 2. Add the following line to your CMakeLists.txt:

      #      include(CodeCoverage)

      #

      # 3. Append necessary compiler flags:

      #      APPEND_COVERAGE_COMPILER_FLAGS()

      #

      # 4. If you need to exclude additional directories from the report, specify them

      #    using the COVERAGE_EXCLUDES variable before calling SETUP_TARGET_FOR_COVERAGE.

      #    Example:

      #      set(COVERAGE_EXCLUDES 'dir1/*' 'dir2/*')

      #

      # 5. Use the function SETUP_TARGET_FOR_COVERAGE to create a custom make target

      #    which runs your test executable and produces a lcov code coverage report:

      #    Example:

      #      SETUP_TARGET_FOR_COVERAGE(

      #          my_coverage_target  # Name for custom target.

      #          test_driver         # Name of the test driver executable that runs the tests.

      #                              # NOTE! This should always have a ZERO as exit code

      #                              # otherwise the coverage generation will not complete.

      #          coverage            # Name of output directory.

      #      )

      #

      # 6. Build a Debug build:

      #      cmake -DCMAKE_BUILD_TYPE=Debug ..

      #      make

      #      make my_coverage_target
