+# - CodeCoverage
+# Generate code coverage reports with LCOV and GCovr.
+#
+# Configuration:
+#  COVERAGE_SOURCE_DIR      - Source root directory (default ${CMAKE_SOURCE_DIR}).
+#  COVERAGE_BINARY_DIR      - Directory where the coverage reports (and intermediate files)
+#                             are generated to.
+#  COVERAGE_EXCLUDES        - List of exclude patterns (for example '*/tests/*').
+#
+# The following targets will be generated:
+#  coverage                 - Builds an html report. Requires LCOV.
+#  coverage_xml             - Builds an xml report (in Cobertura format for Jenkins).
+#                             Requires Gcovr.
