CTest classified "note:" belonging to a warning as warning
Due to "([^ :]+):([0-9]+): note:"
being in the cmCTestWarningMatches
array of regexes in Source/CTest/cmCTestBuildHandler.cxx#L103, it seems "note: ..." messages belonging to a warning already counted as such are counted as warnings in of themselves.
Example:
This is one warning presented as three due to the classfication of "note:" as a warning.
