+# - Enable Code Coverage
+#
+# 2013-09-17, Joakim Söderberg
+# - Added support for Clang.
+# - Some additional usage instructions.
+#
+# USAGE:
+
+# 0. (Mac only) If you use Xcode 5.1 make sure to patch geninfo as described 
here:
+#      http://stackoverflow.com/a/22404544/80480
+#
+# 1. Copy this file into your cmake modules path.
+#
+# 2. Add the following line to your CMakeLists.txt:
+#      INCLUDE(CodeCoverage)
+#
+# 3. Set compiler flags to turn off optimization and enable coverage:
+#    SET(CMAKE_CXX_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
+#       SET(CMAKE_C_FLAGS "-g -O0 -fprofile-arcs -ftest-coverage")
+#
+# 3. 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.
+#                              )
+#
+# 4. Build a Debug build:
+#       cmake -DCMAKE_BUILD_TYPE=Debug ..
+#       make
+#       make my_coverage_target
+#
+#
+
+# Check prereqs
