URL: https://issues.apache.org/jira/browse/MADLIB-1138
Project: Apache MADlib
Issue Type: Task
Components: Build System
Reporter: Ed Espino

party metrics will be filtered out of coverage info file and stored in
CodeCoverage-filtered.info
* HTML report will be created in build/CodeCoverageReport directory
Usage:
* cmake -DENABLE_COVERAGE=ON ..
* <build, install and execute desired tests as usual>
