Cppcheck support in CMake

Question

I am not asking about the various available third-party modules that support Cppcheck anyway.

With CMake 3.10, CMake seems to have received some official support from Cppcheck. See _CPPCHECK rel = "nofollow noreferrer"> CMAKE_ <LANG> _CPPCHECK .

Unfortunately, the documentation on how to use this variable is a bit sparse. Is there a good example of how Cppcheck is supposed to be used with CMake 3.10 (or later)?

Answer 1

A simple example could be - if you have cppcheckin yours PATHand you do not specify additional parameters - the following, setting the global : CMAKE_<LANG>_CPPCHECK

cmake_minimum_required(VERSION 3.10)

project(CppCheckTest)

file(
    WRITE "main.cpp"
[=[
int main()
{
    char a[10];
    a[10] = 0;
    return 0;
}
]=] 
)

set(CMAKE_CXX_CPPCHECK "cppcheck")
add_executable(${PROJECT_NAME} "main.cpp")

cppcheck. , (gcc cppcheck Linux):

# make
Scanning dependencies of target CppCheckTest
[ 50%] Building CXX object CMakeFiles/CppCheckTest.dir/main.cpp.o

Warning: cppcheck reported diagnostics:

[100%] Linking CXX executable CppCheckTest

cppcheck , CMAKE_CXX_CPPCHECK cmake:

# cmake -DCMAKE_CXX_CPPCHECK:FILEPATH=cppcheck ..

"" , , CMakeList.txt - :

find_program(CMAKE_CXX_CPPCHECK NAMES cppcheck)
if (CMAKE_CXX_CPPCHECK)
    list(
        APPEND CMAKE_CXX_CPPCHECK 
            "--enable=warning"
            "--inconclusive"
            "--force" 
            "--inline-suppr"
            "--suppressions-list=${CMAKE_SOURCE_DIR}/CppCheckSuppressions.txt"
    )
endif()
