 #
 # CHANGES:
 #
 # 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_LCOV_EXCLUDES variable before calling SETUP_TARGET_FOR_COVERAGE_LCOV.
 #    Example:
 #      set(COVERAGE_LCOV_EXCLUDES 'dir1/*' 'dir2/*')
 #
 # 5. Use the functions described below to create a custom make target which
 #    runs your test executable and produces a code coverage report.
 #
 # 6. Build a Debug build:
 #      cmake -DCMAKE_BUILD_TYPE=Debug ..
 #      make
 #      make my_coverage_target
 #
