CMake如何在多平台项目中统一管理Sanitizer设置?

CMake在多平台项目中管理Sanitizer(如AddressSanitizer、UndefinedBehaviorSanitizer等)设置时,可以通过添加`target_compile_options`或`add_definitions`指令来实现。这允许你在编译时指定特定的调试选项,以启用Sanitizer检查。以下是一个示例:
```cmake
# 在CMakeLists.txt中
if(${CMAKE_SYSTEM_NAME} MATCHES "Linux")
target_compile_options(MyProject PRIVATE -fsanitize=address)
elseif(${CMAKE_SYSTEM_NAME} MATCHES "Darwin")
target_compile_options(MyProject PRIVATE -sanitize=address)
else()
message(FATAL_ERROR "Unsupported platform for Sanitizer")
endif()
# 或者针对特定模块
add_definitions(-DSANITIZE_ADDRESS)
# 如果你想要动态调整这些设置,你可以创建一个模块来封装这些逻辑
function(set_sanitizer_flags _name)
if(${CMAKE_SYSTEM_NAME} MATCHES "Linux")
set_property(TARGET ${_name} PROPERTY COMPILE_FLAGS "-fsanitize=${ARGN}")
elseif(${CMAKE_SYSTEM_NAME} MATCHES "Darwin")
set_property(TARGET ${_name} PROPERTY COMPILE_FLAGS "-sanitize=${ARGN}")
endif()
endfunction()
set_sanitizer_flags(MyProject Address)
```
这样,Sanitizer会在匹配相应操作系统的构建环境中被启用。记得要确保你的构建工具链支持这些选项,并在每个目标上正确应用。
