Cppcheck 与 CMake 集成用于某些目标

如何解决Cppcheck 与 CMake 集成用于某些目标

我无法弄清楚的是，如果我有一个 CMake 项目，其子文件夹包含自己的 CMakeLists.txt 和自己的目标： 我想为特定目标而不是所有目标集成 Cppcheck。 那么在这种情况下，我需要在根 CMakeLists.txt 中包含哪些内容，以及子文件夹的 CMakeLists 会发生什么变化？

解决方法

为每个您想要检查的目标设置 <LANG>_CPPCHECK 目标属性，并从您不想使用 cppcheck 检查的每个目标中清除它。

以下 CMakeLists.txt 文件：

cmake_minimum_required (VERSION 3.11)
project(test)
file(WRITE a.c "int main() { int a[10]; a[10] = 0; }")
file(WRITE b.c "int main() { int b[10]; b[10] = 0; }")
file(WRITE c.c "int main() { int c[10]; c[10] = 0; }")
file(WRITE a.h "static inline void f() { int a[10]; a[10] = 0; }")
file(WRITE b.h "static inline void f() { int b[10]; b[10] = 0; }")
file(WRITE c.h "static inline void f() { int c[10]; c[10] = 0; }")
add_executable(a a.c a.h)
add_executable(b b.c b.h)
add_executable(c c.c c.h)
set(cppcheck
  cppcheck
  "--enable=warning"
  "--inconclusive"
  "--force" 
  "--inline-suppr"
)
set_target_properties(a PROPERTIES C_CPPCHECK ${cppcheck})
set_target_properties(b PROPERTIES C_CPPCHECK ${cppcheck})

结果只检查a.c和b.c文件，没有检查c.c文件。
