// This file contains enough suppressions to result in no cppcheck warnings,
// at least on Mac OS X with cppcheck 1.74.

// To run:
// cd /path/to/VTK/
// cppcheck --platform=unix64 --enable=style -q --suppressions-list=CMake/VTKcppcheckSuppressions.txt --template='{id},{file}:{line},{severity},{message}' -j8 .

// Suppress everything from ThirdParty.

// Similarly, these aren't really part of VTK proper.
*:Utilities/KWSys/*
*:Utilities/MetaIO/*
*:Utilities/DICOMParser/*

// Can't fix in portable way for all VTK-supported platforms.
