CMake配置说明
Examples CMake工程结构

主CMakeLists.txt说明
下面从根目录的CMakeLists.txt开始介绍：- 设置需要使用CMake的最低版本为3.1.15
cmake_minimum_required(VERSION 3.1.15)
- 生成一个名为OrbbecSDK-Examples工程，使用C++和C语言
project(OrbbecSDK-Examples LANGUAGES CXX C)
- 使用标准的C++ 11进行编译
set(CMAKE_CXX_STANDARD 11)set(CMAKE_CXX_STANDARD_REQUIRED True)
- 设置SDK的头文件及库路径
set(OBSensor_DIR ${CMAKE_SOURCE_DIR}/../SDK)set(OBSensor_LIBRARY_DIRS ${OBSensor_ROOT_DIR}/lib/${CMAKE_BUILD_TYPE})set(OBSensor_INCLUDE_DIR ${OBSensor_ROOT_DIR}/include)include_directories(${OBSensor_INCLUDE_DIR})link_directories(${OBSensor_LIBRARY_DIRS})
- 查找opencv库
# set(OpenCV_DIR "your/path/to/opencv") # 可通过该命令指定OpenCV_DIR模块查找路径find_package(OpenCV QUIET)if(${OpenCV_FOUND})include_directories(${OpenCV_INCLUDE_DIR})link_directories(${OpenCV_LIBRARY_DIRS})ENDIF(${OpenCV_FOUND})
- 设置ARCHIVE、LIBRARY、RUNTIME的输出目录，
set(CMAKE_ARCHIVE_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)set(CMAKE_LIBRARY_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/lib)set(CMAKE_RUNTIME_OUTPUT_DIRECTORY ${CMAKE_BINARY_DIR}/bin)
| Windows | Unix | |
|---|---|---|
| RUNTIME | .exe、.dll | 可执行程序 |
| LIBRARY | .so | |
| ARCHIVE | .a、.lib | .a |
- 添加子工程目录
add_subdirectory(c)add_subdirectory(cpp)
C语言版本Examples 主CMakeLists说明
``` cmake_minimum_required(VERSION 3.1.15)
opencv required
IF(${OpenCV_FOUND}) add_subdirectory(Sample-ColorViewer) add_subdirectory(Sample-DepthViewer) add_subdirectory(Sample-InfraredViewer) add_subdirectory(Sample-PointCloud) add_subdirectory(Sample-NetDevice) ENDIF(${OpenCV_FOUND})这个文件比较简单，这里做一个简要说明。主要是根据是否有查找到opencv库及各example属性是否依赖opencv库决定是否将该example添加到工程。## C语言版本Examples 子CMakeLists说明在各Example子目录下包含各自的CMakeLists.txt, 以Sample-HelloOrbbec为例:
内容比较简单，主要是指定将源文件HelloOrbbec.c生产可执行文件hello_orbbec（windows平台生成文件待.exe后缀），并指定连接obsensor库。## C++版本Examples 主CMakeLists说明
opencv required
IF(${OpenCV_FOUND}) add_subdirectory(Sample-ColorViewer) add_subdirectory(Sample-DepthViewer) add_subdirectory(Sample-InfraredViewer) add_subdirectory(Sample-SyncAlignViewer) add_subdirectory(Sample-HotPlugin) add_subdirectory(Sample-PointCloud) add_subdirectory(Sample-MultiDevice) add_subdirectory(Sample-MultiDeviceSync) add_subdirectory(Sample-NetDevice) add_subdirectory(Sample-SaveToDisk) add_subdirectory(Sample-Recorder) add_subdirectory(Sample-Playback) ENDIF(${OpenCV_FOUND})C++版本Examples 主CMakeLists.txt目标和内容和C语言版本基本一致，这里不再赘述。不同的是C++版本提供了更为丰富的例程。## C++版本Examples 子CMakeLists说明与C语言版本基本一致，这里不再复述。
