为什么在cmake构建之后不维护原始项目目录结构（参见Xcode项目文件.xcodeproj）

下面是我的目录结构，我想使用cmake生成一个cmake文件（.xcodeproj/codeBlock项目文件，用于ubuntu，或者只是一个简单的make文件）

├── ExternalLibs
│   ├── license.txt
│   ├── rapidxml.hpp
│   ├── rapidxml_iterators.hpp
│   ├── rapidxml_print.hpp
│   └── rapidxml_utils.hpp
├── FeatureExtractors
│   ├── FeatureExtactors.cpp
│   ├── HarrisKeyPoint.cpp
│   └── hdr
│       ├── BlurVarietyEnums.h
│       ├── CompressionVarietyEnums.h
│       ├── DescriptorExtractorType.h
│       ├── DescriptorMatcherType.h
│       ├── FeatureDetectorType.h
│       ├── FeatureExtactors.hpp
│       ├── HarrisKeyPoint.hpp
│       ├── ILLuminationVarietyEnums.h
│       ├── NoiseVarietyEnums.h
│       ├── OutlierFilter.h
│       └── openCVFeatureDetectorsExtractors.h
├── ImageProcessing
│   ├── ImageDeformationOperations.cpp
│   ├── ImageEnhancement.cpp
│   ├── MannualAdjustments.cpp
│   └── hdr
│       ├── Deforming_of_Image.hpp
│       ├── ImageDeformationOperations.hpp
│       ├── ImageEnhancement.hpp
│       └── MannualAdjustments.hpp
├── KeyPointDetectionTechniques.cpp
├── KeyPointEvaluation.cpp
├── Products
├── hdr
│   └── KeyPointDetectionTechniques.hpp
└── util
    ├── BasicAlgo.cpp
    ├── BasicAlgosUsingTemplates.cpp
    ├── DirectoryHandler.cpp
    ├── TiffImageReader.cpp
    └── hdr
        ├── BasicAlgo.h
        ├── BasicAlgosUsingTemplates.hpp
        ├── DirectoryHandler.hpp
        └── TiffImageReader.hpp

以下是我的CMakeLists.txt中使用的命令

cmake_minimum_required(VERSION 2.8.9)
PROJECT(KeyPointEvaluation CXX)
SET( PROJ_NAME  "KeyPointEvaluation" )
set(CMAKE_BUILD_TYPE Release)

对于openCv库

find_package( OpenCV REQUIRED )

这些是目录，我想我应该一个接一个地包含它们，以保持相同的目录结构

#Bring the headers and other files needed for the project to complile
SET( PROJ_INCLUDES  "ExternalLibs" "FeatureExtractors" "hdr" "ImageProcessing" "Products" "util")

同样，为了在生成构建后拥有与最初相同的项目目录结构，我做了以下工作

#Can manually add the sources using the set command as follows:
FILE( GLOB_RECURSE PROJ_SOURCES "FeatureExtractors/*.cpp" "ImageProcessing/*.cpp" "util/*.cpp"  )
FILE( GLOB_RECURSE PROJ_HEADERS "FeatureExtractors/hdr/*.h" "FeatureExtractors/hdr/*.hpp" "hdr/*.h" "ImageProcessing/hdr/*.hpp" "util/hdr/*.hpp" "util/hdr/*.h" "ExternalLibs/hdr/*.hpp")

添加openCv、源代码和标题

INCLUDE_DIRECTORIES( ${PROJ_INCLUDES} )
ADD_EXECUTABLE( ${PROJ_NAME} ${PROJ_SOURCES} ${PROJ_HEADERS})
target_link_libraries( KeyPointEvaluation ${OpenCV_LIBS} )

现在的问题是，在CMake构建之后，所有源文件都放在一个文件夹中，所有头文件都放在另一个文件夹中。但是，我想保持原来的目录结构

请告诉我，我应该修改CMakeLists.txt文件中的任何内容，以获得与原来相同的目录结构

不要使用文件（GLOB_RECURSE），而是执行以下操作：

set ( PROJ_SOURCES
"path/to/source1.cpp"
"path/to/source2.cpp"
)
set ( PROJ_HEADERS
"path/to/source1.h"
"path/to/source2.h"
)

source_group(TREE "${CMAKE_CURRENT_LIST_DIR}" FILES ${PROJ_SOURCES})
source_group(TREE "${CMAKE_CURRENT_LIST_DIR}" FILES ${PROJ_HEADERS})

您可以通过添加前缀来添加额外的结构，例如：

source_group(TREE "${CMAKE_CURRENT_LIST_DIR}" PREFIX "ExtraFolderName" FILES ${PROJ_SOURCES})
