Sources may be either file names or directories containing files +# where all C/++ files will be parsed automatically. Use directories whenever +# possible because there is a limitation in arguments to pass to the cppcheck +# binary. +# +# SUPPRESSION_FILE may be given additionally to specify suppressions for +# cppcheck. The sources mentioned in the suppression file must be in the same +# format as given for SOURCES. This means if you specify them relative to +# CMAKE_CURRENT_SOURCE_DIR, then the same relative paths must be used in the +# suppression file. +# +# ENABLE_IDS allows to specify which additional cppcheck check ids to execute, +# e.g. all or style. +# +# With TARGET_NAME a different name for the generated check target can be +# specified. This is useful if several calls to this function are made in one +# CMake project, as otherwise the target names would collide. +# +# Additional include directories for the cppcheck program can be given with +# INCLUDES. +# +# cppcheck will be executed with CMAKE_CURRENT_SOURCE_DIR as working directory. +# +# This function can be called even if cppcheck wasn't found. In that case no +# target is created. +# +# + +#============================================================================= +# Copyright 2011 Johannes Wienke <jwienke at techfak dot uni-bielefeld dot de> +# Copyright 2012 Přemysl Janouch <p.janouch at gmail dot com> +# All rights reserved. +# +# Redistribution and use in source and binary forms, with or without +# modification, are permitted provided that the following conditions are met: +# * Redistributions of source code must retain the above copyright +# notice, this list of conditions and the following disclaimer. +# * Redistributions in binary form must reproduce the above copyright +# notice, this list of conditions and the following disclaimer in the +# documentation and/or other materials provided with the distribution. +# +# THIS SOFTWARE IS PROVIDED BY THE COPYRIGHT HOLDERS AND CONTRIBUTORS ``AS IS'' +# AND ANY EXPRESS OR IMPLIED WARRANTIES, INCLUDING, BUT NOT LIMITED TO, +# THE IMPLIED WARRANTIES OF MERCHANTABILITY AND FITNESS FOR A PARTICULAR +# PURPOSE ARE DISCLAIMED.
