OrangesCppcheck

Provides functions to set up the cppcheck static analysis tool.

Configure cppcheck for a target

oranges_enable_cppcheck

oranges_enable_cppcheck (<target>
                        [ENABLE <checks...>]
                        [DISABLE <checks...>]
                        [EXTRA_ARGS <args...>]
                        [LANGS <C|CXX>...])

Configures cppcheck for the given <target> by manipulating the target’s <LANG>_CPPCHECK properties.

If the CPPCHECK_OFF variable is set to ON, this function does nothing.

Options:

ENABLE

A list of checks to enable for this target. If not specified, the value of the CPPCHECK_ENABLE variable will be used.

DISABLE

A list of checks to disable for this target. If not specified, the value of the CPPCHECK_DISABLE variable will be used.

EXTRA_ARGS

A list of extra arguments to pass to cppcheck verbatim. If not specified, the value of the CPPCHECK_EXTRA_ARGS variable will be used.

LANGS

Languages for which to enable cppcheck. Valid values are C or CXX. If no languages are specified, this function will configure cppcheck for both valid languages.

Configure cppcheck globally

oranges_create_cppcheck_target

oranges_create_cppcheck_target ([ENABLE <checks...>]
                                [DISABLE <checks...>]
                                [EXTRA_ARGS <args...>])

Creates a custom target named cppcheck that executes cppcheck over the entire source tree.

If the CPPCHECK_OFF variable is set to ON, this function does nothing.

Note that all arguments are optional. Options:

ENABLE

A list of checks to enable. If not specified, the value of the CPPCHECK_ENABLE variable will be used.

DISABLE

A list of checks to disable. If not specified, the value of the CPPCHECK_DISABLE variable will be used.

EXTRA_ARGS

A list of extra arguments to pass to cppcheck verbatim. If not specified, the value of the CPPCHECK_EXTRA_ARGS variable will be used.

Cache variables

CPPCHECK_PROGRAM

Path to the cppcheck executable, used by oranges_enable_cppcheck(). An environment variable with this name may also be set.

CPPCHECK_ENABLE

A space-separated list of default cppcheck checks to be enabled with calls to oranges_enable_cppcheck() that do not explicitly list their own desired checks. The environment variable with this name, if set, will initialize this variable’s value; otherwise, a default set of checks will be enabled.

CPPCHECK_DISABLE

A space-separated list of default cppchecks checks to be disabled with calls to oranges_enable_cppcheck() that do not explicitly list their own desired disabled checks. The environment variable with this name, if set, will initialize this variable’s value; otherwise, a default set of checks will be disabled.

CPPCHECK_EXTRA_ARGS

A list of space-separated arguments that will be passed to cppcheck verbatim in calls to oranges_enable_cppcheck(). The environment variable with this name, if set, will initialize this variable’s value; otherwise, defaults to --inline-suppr.

CPPCHECK_OFF

When this variable is set to ON, calls to oranges_enable_cppcheck() do nothing. The environment variable with this name, if set, will initialize this variable; otherwise, defaults to OFF.

Environment variables

CPPCHECK_PROGRAM

Initializes the value of the CPPCHECK_PROGRAM variable.

CPPCHECK_ENABLE

Initializes the CPPCHECK_ENABLE variable.

CPPCHECK_DISABLE

Initializes the CPPCHECK_DISABLE variable.

CPPCHECK_EXTRA_ARGS

Initializes the CPPCHECK_EXTRA_ARGS variable.

CPPCHECK_OFF

Initializes the CPPCHECK_OFF variable.
