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！
