CMake迭代遍历文件夹，建立过滤器

vs下cmake遍历文件夹并建立过滤器

function(retrieve_files out_files)
    set(source_list)
    foreach(dirname ${
  ARGN})
        file(GLOB_RECURSE files RELATIVE ${
  CMAKE_CURRENT_SOURCE_DIR}
			"${dirname}/*.cmake"
            "${dirname}/*.h"
            "${dirname}/*.hpp"
            "${dirname}/*.c"
            "${dirname}/*.cpp"
            "${dirname}/*.cc"            
        )
        foreach(filename ${
  files})
            list(APPEND source_list "${CMAKE_CURRENT_SOURCE_DIR}/${filename}")
			set(file_abs_path "${CMAKE_CURRENT_SOURCE_DIR}/${filename}")
			get_filename_component(source_path "${filename}" PATH)
            string(REPLACE "/" "\\" filter_dir "${source_path}")
            source_group("${filter_dir}" FILES "${filename}")
        endforeach()
    endforeach()
    set(${
  out_files} ${
  source_list} PARENT_SCOPE)
endfunction()
