CMake在Visual Studio下保持目录结构

原理

主要通过CMAKE自带函数source_group来设定。
需要把add_executable()函数进行封装，包裹一层source_group()的处理

例子

现有目录结构

hello/include/hello.hpp
hello/src/hello.cpp
hello/CMakeLists.txt

编写CMakeLists.txt

cmake_minimum_required(VERSION 3.1)

project(hello)

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)

function(my_add_executable)
    foreach(_source IN ITEMS ${ARGN})
        assign_source_group(${_source})
    endforeach()
    add_executable(${ARGV})
endfunction(my_add_executable)

my_add_executable(hello include/hello.hpp src/hello.cpp)

执行编译

cd hello
mkdir build
cd build
cmake .. -G "Visual Studio 14 Win64"
cmake --build .

打开hello/build/hello.sln看看，是不是好了！
