# - Generate a cppcheck documentation for a project. # The function GENERATE_CPPCHECK is provided to create a "cppcheck" target that # performs static code analysis using the cppcheck utility program. # # GENERATE_CPPCHECK(SOURCES <sources to check...> # [SUPPRESSION_FILE <file>] # [ENABLE_IDS <id...>] # [TARGET_NAME <name>] # [INCLUDES <dir...>]) # # Generates a target "cppcheck" that executes cppcheck on the specified sources. # Sources may either be 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 give additionally to specify suppressions for# # cppcheck. The sources mentioned in the suppression file must be in the same # format like given for SOURCES. This means if you specified 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. They are combined with AND. # With TARGET_NAME a different name for the generated check target can be # specified. This is useful if several calles to this function are made in one # CMake project, as otherwise the target names 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 always be called, even if no cppcheck was found. Then no # target is created. # # Copyright (C) 2011 by Johannes Wienke <jwienke at techfak dot uni-bielefeld dot de> # # This program is free software; you can redistribute it # and/or modify it under the terms of the GNU General # Public License as published by the Free Software Foundation; # either version 2, or (at your option) # any later version. # # This program is distributed in the hope that it will be useful, # but WITHOUT ANY WARRANTY; without even the implied warranty of # MERCHANTABILITY or FITNESS FOR A PARTICULAR PURPOSE.
