cmake - 在 CMake 中为每个目标设置 CXX_INCLUDE_WHAT_YOU_USE 属性

Question

我的项目中有多个 CmakeLists.txt，我想启用iwyu.

添加

set_property(
  TARGETS MY-TARGET
  PROPERTY CXX_INCLUDE_WHAT_YOU_USE ${iwyu_path}
)

将为一个目标启用它。我想为每个目标启用它，以避免在我包含在已经存在的 CMakeLists.txt 中的另一个 file.cmake 中出现冗余。

Answer 1

cmake_minimum_required(VERSION 3.3 FATAL_ERROR)

find_program(IWYU_PATH NAMES include-what-you-use iwyu)
if(NOT IWYU_PATH)
  message(FATAL_ERROR "Could not find the program include-what-you-use")
endif()
set(CMAKE_CXX_INCLUDE_WHAT_YOU_USE ${IWYU_PATH})
set(CMAKE_C_INCLUDE_WHAT_YOU_USE ${IWYU_PATH})
