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。

新增中

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

将使它成为一个目标。我想为每个目标启用它，以避免在另一个文件中产生冗余。我在已经存在的CMakeLists.txt中添加了该文件。

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})

可以在这里找到“文档”：CMAKE_ <LANG> _INCLUDE_WHAT_YOU_USE
