# -----------------------------------------------------------------------------
#                LUFA CPPCheck Buildsystem Makefile Module.
# -----------------------------------------------------------------------------
# DESCRIPTION:
#   Provides a set of targets to scan a project with the free "cppcheck" static
#   analysis tool, to check for code errors at runtime (see http://cppcheck.sourceforge.net).
# -----------------------------------------------------------------------------
# TARGETS:
#
#    cppcheck                  - Scan the project with CPPCheck
#    cppcheck-config           - Use CPPCheck to look for missing include files
#
# MANDATORY PARAMETERS:
#
#    (None)
#
# OPTIONAL PARAMETERS:
#
#    CPPCHECK_PATH             - Path of the files to statically analyze
#    CPPCHECK_INCLUDES         - Extra include paths to search for missing
#                                header files
#    CPPCHECK_EXCLUDES         - Source file paths to exclude checking (can be
#                                a path fragment if desired)
#    CPPCHECK_MSG_TEMPLATE     - Template for cppcheck error and warning output
#    CPPCHECK_ENABLE           - General cppcheck category checks to enable
#    CPPCHECK_SUPPRESS         - Specific cppcheck warnings to disable by ID
#    CPPCHECK_FAIL_ON_WARNING  - Set to Y to fail the build on cppcheck
#                                warnings, N to continue even if warnings occur
#    CPPCHECK_QUIET            - Enable cppcheck verbose or quiet output mode
#    CPPCHECK_FLAGS            - Additional flags to pass to cppcheck
#
