CMake 按照文件目录组织VS工程的筛选器

macro(group_src_by_dir src_files)
    foreach(file_path ${${src_files}})
        string(REGEX REPLACE ${CMAKE_CURRENT_SOURCE_DIR}/(.*) \1 relative_path ${file_path})
        string(REGEX MATCH ".+\.c.*" is_match ${relative_path})
        if(is_match)
            string(REGEX REPLACE "(.+)\.c.*" \1 cpp_relative_dir ${relative_path})
            if(NOT cpp_relative_dir STREQUAL "main")
                list(APPEND c_groups ${cpp_relative_dir})
            endif()
        endif(is_match)
    endforeach(file_path)
    
    foreach(file_path ${${src_files}})
        message(${file_path})
        string(REGEX REPLACE ${CMAKE_CURRENT_SOURCE_DIR}/(.*) \1 relative_path ${file_path})
        string(REGEX REPLACE "(.+)\..*" \1 relative_group ${relative_path})
        list(FIND c_groups ${relative_group} index)
        if(NOT index LESS 0)
            message(${relative_group})
            string(REPLACE "/" "\" relative_group ${relative_group})
            source_group(${relative_group} FILES ${file_path})
        else()
            string(REGEX MATCH "(.+)/.*" has_group ${relative_path})
            if(has_group)
                string(REGEX REPLACE "(.+)/.*" \1 group ${relative_path})
                string(REPLACE "/" "\" group ${group})
                message(${group})
                source_group(${group} FILES ${file_path})
            else()
                message("")
                source_group("" FILES ${file_path})
            endif()
        endif()
    endforeach(file_path)
endmacro(group_src_by_dir)

该函数有两个效果:

1.按照代码文件在磁盘的目录结构来组织VS的筛选器结构

2.如果同一个目录下包含同名的.cpp和.h文件,则会将这两个文件组织到同一个筛选器中.

效果:
