问题：

使用 cmake 编译工程时，显示项目所包含的头文件。

其列出的头文件所包含的内容经过递归检索。

如下：

原因：

使用了 showIncludes 选项。

选项链接：https://learn.microsoft.com/zh-cn/cpp/build/reference/showincludes-list-include-files?view=msvc-170

使用该选项会列出所有头文件信息。

解决方案：

cmake 添加函数

# # 取消显示包含头文件内容 function( un_show_include_info target_name ) # 关闭 /showIncludes if( MSVC ) message( STATUS "使用 MSVC 编译环境" ) # 检查是否存在编译选项 if( CMAKE_DEPFILE_FLAGS_CXX ) # 移除 /showIncludes 编译选项 list( REMOVE_ITEM CMAKE_DEPFILE_FLAGS_CXX "/showIncludes" ) string( REPLACE "/showIncludes" "" CMAKE_DEPFILE_FLAGS_CXX "${CMAKE_DEPFILE_FLAGS_CXX}" ) set( CMAKE_DEPFILE_FLAGS_CXX ${CMAKE_DEPFILE_FLAGS_CXX} PARENT_SCOPE ) endif( ) # 检查是否存在编译选项 if( CMAKE_DEPFILE_FLAGS_C ) # 移除 /showIncludes 编译选项 list( REMOVE_ITEM CMAKE_DEPFILE_FLAGS_C "/showIncludes" ) string( REPLACE "/showIncludes" "" CMAKE_DEPFILE_FLAGS_C "${CMAKE_DEPFILE_FLAGS_C}" ) set( CMAKE_DEPFILE_FLAGS_C ${CMAKE_DEPFILE_FLAGS_C} PARENT_SCOPE ) endif( ) # 获取目标的当前编译选项 get_target_property( TARGET_COMPILE_OPTIONS ${target_name} COMPILE_OPTIONS ) # 检查是否存在编译选项 if( TARGET_COMPILE_OPTIONS ) # 移除 /showIncludes 编译选项 list( REMOVE_ITEM TARGET_COMPILE_OPTIONS "/showIncludes" ) # 更新目标的编译选项 set_target_properties( ${target_name} PROPERTIES COMPILE_OPTIONS "${TARGET_COMPILE_OPTIONS}" ) endif( ) # 检查是否存在编译选项 if( CMAKE_CXX_SCANDEP_SOURCE ) # 移除 /showIncludes 编译选项 list( REMOVE_ITEM CMAKE_CXX_SCANDEP_SOURCE "/showIncludes" ) list( REMOVE_ITEM CMAKE_CXX_SCANDEP_SOURCE "-showIncludes" ) string( REPLACE "/showIncludes" "" CMAKE_CXX_SCANDEP_SOURCE "${CMAKE_CXX_SCANDEP_SOURCE}" ) string( REPLACE "-showIncludes" "" CMAKE_CXX_SCANDEP_SOURCE "${CMAKE_CXX_SCANDEP_SOURCE}" ) set( CMAKE_CXX_SCANDEP_SOURCE ${CMAKE_CXX_SCANDEP_SOURCE} PARENT_SCOPE ) endif( ) endif( ) endfunction( un_show_include_info )

调用

add_executable( ${prject_name} ${project_src_file} ) un_show_include_info( ${prject_name} )
