 # 2012-01-31, Lars Bilke
 # - 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
