在Linux上使用Cmake时，我该如何告诉PVS-Studio忽略第三方库中的所有文件

Question

我正在使用Linux上的cmake使用PVS-Studio。我最近在我的项目中添加了第三方库。

PVS-Studio正在为第三方库的标题文件中标记可能的问题。在分析我的代码时，我该如何告诉PVS-Studio忽略整个第三方库？当在Windows上使用PVS-Studio与Visual Studio一起使用时，我可以使用Visual Studio内的PVS-Studio扩展来执行此操作。在Linux上我没有。

我已经将我的cmakelists.txt文件附加到了此项目(非常简单(，加上PVS-Studio发出的警告列表。

cmakelists.txt

cmake_minimum_required(VERSION 3.15.0)
set(CMAKE_CXX_FLAGS "${CMAKE_CXX_FLAGS} -Wall")
project(my_project)
include_directories($ENV{HOME}/code/repo/other/GSL/include)
set(CMAKE_CXX_STANDARD 17)
set(CMAKE_CXX_STANDARD_REQUIRED ON)
set(CMAKE_CXX_EXTENSIONS OFF)
set(proj_srcs main.cpp notes.txt)
add_executable(${PROJECT_NAME} ${proj_srcs})
include($ENV{HOME}/code/repo/other/pvs-studio-cmake-examples/PVS-Studio.cmake)
pvs_studio_add_target(TARGET ALL COMPILE_COMMANDS OUTPUT FORMAT errorfile)

警告

.../other/GSL/include/gsl/multi_span:663:1: warning: V547 Expression is always true.
.../other/GSL/include/gsl/multi_span:1163:1: warning: V560 A part of conditional expression is always true: totalSize <= (9223372036854775807L).
.../other/GSL/include/gsl/string_span:118:1: warning: V547 Expression 'cur != nullptr' is always true.

我仍然很难让它起作用。

在cmakelists.txt中我有：

# The header files for the C++ Standard Library are located in /usr/include.
# Unfortunately ARGS --exclude-path /usr/include does not suppress the warnings
# generated by Clang.
pvs_studio_add_target(TARGET ALL COMPILE_COMMANDS OUTPUT FORMAT errorfile ARGS --exclude-path /usr/include)

用叮当声构建12.0.0 x86_64-pc-linux-gnu pvs studio会产生数百条警告。例如，

--- snip ---
/include/c++/10/bits/stl_numeric.h:64:1: warning: V1061 Extending the 'std' namespace may result in undefined behavior.
/include/c++/10/numeric:80:1: warning: V1061 Extending the 'std' namespace may result in undefined behavior.
/include/c++/10/numeric:167:1: warning: V1061 Extending the 'std' namespace may result in undefined behavior.
/include/c++/10/numeric:226:1: warning: V1061 Extending the 'std' namespace may result in undefined behavior.
/include/c++/10/pstl/glue_numeric_defs.h:15:1: warning: V1061 Extending the 'std' namespace may result in undefined behavior.
--- snip ---

有人知道可能是什么问题吗？

谢谢，

您可以使用此参数：

-e [DIR], --exclude-path [DIR]
   Directory whose files are not necessary to check

cmakelists.txt：

pvs_studio_add_target(TARGET ALL
                      COMPILE_COMMANDS
                      OUTPUT FORMAT errorfile
                      ARGS -e /path/to/third/party -e /path/to/tests)
