This patch adds a `coverage` target that allows coverage statisitics to be retrieved for the project. It requires that lcov and gcov is installed and that the generator is unix makefiles but this can be improved upon in future releases. To make it work use the coverage build type: ``` cmake -DCMAKE_BUILD_TYPE=Coverage . make coverage ```
