如何使用 cmake 为嵌套子目录设置 Visual Studio 过滤器

问题描述

我有以下结构

Main (dir)
      +-- CMakeLists.txt
      +-- File.cpp
      +-- File.hpp
      +-- Dir (dir)
          +-- CMakeLists.txt
          +-- File1.cpp
          +-- File1.hpp
          +-- File2.cpp
          +-- File2.hpp

Main/CMakeLists.txt

CMAKE_MINIMUM_REQUIRED (VERSION 2.8.11)
PROJECT(Main)
FILE(GLOB SOURCE
    "*.hpp"
    "*.cpp"
)

ADD_SUBDIRECTORY(Dir)
ADD_EXECUTABLE(Main ${SOURCE})

Main/Dir/CmakeLists.txt

FILE(GLOB LOCAL_SOURCE
    "*.hpp"
    "*.cpp"
)
SET(SOURCE
    ${SOURCE}
    ${LOCAL_SOURCE}
    PARENT_SCOPE
)

它在 Visual Studio 中生成了以下结构

It generated the following structure in Visual Studio

我想要的:

我的尝试:

Main/CMakeLists.txt

CMAKE_MINIMUM_REQUIRED (VERSION 2.8.11)
PROJECT(Main)
FILE(GLOB LOCAL_SOURCE
    "*.hpp"
    "*.cpp"
)

SET(SOURCE 
    ${LOCAL_SOURCE}
)

ADD_SUBDIRECTORY(Dir)

SOURCE_GROUP(Main FILES ${LOCAL_SOURCE})
ADD_EXECUTABLE(Main ${SOURCE})

Main/Dir/CmakeLists.txt

FILE(GLOB LOCAL_SOURCE
    "*.hpp"
    "*.cpp"
)
SET(SOURCE
    ${SOURCE}
    ${LOCAL_SOURCE}
    PARENT_SCOPE
)

SOURCE_GROUP(Dir FILES ${LOCAL_SOURCE})

我得到了什么:

请帮我解决这个问题.

• 我不想在带有过滤器的主目录中使用单个 CmakeFile.txt
• 实际结构是多层深嵌套结构.所以请提出适用于任何级别子目录的解决方案

推荐答案

有几个现成的或适应性强的解决方案来模拟源树行为，例如在 Eclipse 中使用 CMake for Visual Studio(例如 ADD_SRC_SUBFOLDER DESTINATION_SRCS 来自 Zobra 或 GroupSources 来自 Luca).

There are several ready to use or adaptable solutions out there to mimic a Source Tree behavior like in Eclipse with CMake for Visual Studio (e.g. ADD_SRC_SUBFOLDER DESTINATION_SRCS from Zobra or GroupSources from Luca).

这是我针对您的用例的简化版本:

Here is my reduced version for your use case:

cmake_minimum_required(VERSION 2.8.10)

project(Main CXX)

set(
    source_list
    "File.cpp"
    "File.hpp"
    "Dir/File1.cpp"
    "Dir/File1.hpp"
    "Dir/File2.cpp"
    "Dir/File2.hpp"
)

add_executable(Main ${source_list})

foreach(source IN LISTS source_list)
    get_filename_component(source_path "${source}" PATH)
    string(REPLACE "/" "\" source_path_msvc "${source_path}")
    source_group("${source_path_msvc}" FILES "${source}")
endforeach()

参见source_group()的文档 你必须用双反斜杠给子目录.

See the documentation of source_group() that you have to give the sub-directories with double backslashes.

出于为什么我将您的 file(GLOB ...) 替换为我喜欢引用 CMake 的 file() 命令文档:

For the reason why I replaced your file(GLOB ...) with a dedicated list of all source files I like to quote from CMake's file() command documentation:

我们不建议使用 GLOB 从以下位置收集源文件列表你的源代码树.如果在源文件中没有 CMakeLists.txt 文件更改添加或删除然后生成的构建系统不知道何时要求 CMake 重新生成.

We do not recommend using GLOB to collect a list of source files from your source tree. If no CMakeLists.txt file changes when a source is added or removed then the generated build system cannot know when to ask CMake to regenerate.

这是我用作函数的故障安全版本(检查绝对路径):

And here is my fail-safe version (that checks for absolute paths) to be used as a function:

function(assign_source_group)
    foreach(_source IN ITEMS ${ARGN})
        if (IS_ABSOLUTE "${_source}")
            file(RELATIVE_PATH _source_rel "${CMAKE_CURRENT_SOURCE_DIR}" "${_source}")
        else()
            set(_source_rel "${_source}")
        endif()
        get_filename_component(_source_path "${_source_rel}" PATH)
        string(REPLACE "/" "\" _source_path_msvc "${_source_path}")
        source_group("${_source_path_msvc}" FILES "${_source}")
    endforeach()
endfunction(assign_source_group)

您将在示例中使用

assign_source_group(${source_list})
