I have a multi-configuration project that creates a cppcheck results file at the end of the build. I gave the plugin the correct path, and it parsed the file successfully.
However, the link to the cppcheck report is on the main project page (instead of being on the page for each configuration), and states the following:

"No valid cppcheck data available

This plugin will not report cppcheck result until there is at least one success or unstable build. "

I think the cppcheck report link should be individual for configurations, since one might pass and the other might fail (different OS, etc).
