+# 2012-01-31, Lars Bilke
+# - Enable Code Coverage
+#
+# 2013-09-17, Joakim Söderberg
+# - Added support for Clang.
+# - Some additional usage instructions.
+#
+# USAGE:
+# 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
