需要将程序封装成service，cmakelist应该怎么写

您可以使用以下的CMakeList文件来将程序封装成service：

cmake_minimum_required(VERSION 3.5)
project(your_service_name)

set(CMAKE_CXX_STANDARD 11)

find_package(catkin REQUIRED COMPONENTS
  roscpp
  std_msgs
)

catkin_package(
  INCLUDE_DIRS include
  LIBRARIES ${PROJECT_NAME}
  CATKIN_DEPENDS roscpp std_msgs
)

include_directories(
  include
  ${catkin_INCLUDE_DIRS}
)

add_library(${PROJECT_NAME}
  src/your_service_file.cpp
)

add_executable(${PROJECT_NAME}_node
  src/your_service_node.cpp
)

target_link_libraries(${PROJECT_NAME}_node
  ${catkin_LIBRARIES}
  ${PROJECT_NAME}
)

install(TARGETS ${PROJECT_NAME} ${PROJECT_NAME}_node
  ARCHIVE DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
  LIBRARY DESTINATION ${CATKIN_PACKAGE_LIB_DESTINATION}
  RUNTIME DESTINATION ${CATKIN_PACKAGE_BIN_DESTINATION}
)

install(DIRECTORY include/${PROJECT_NAME}/
  DESTINATION ${CATKIN_PACKAGE_INCLUDE_DESTINATION}
)

其中，`your_service_name`是您的服务名称，`your_service_file.cpp`是您的服务实现文件，`your_service_node.cpp`是您的服务节点文件。您需要将这些名称替换为您自己的名称。

此外，您需要在`src`目录下创建`your_service_file.cpp`和`your_service_node.cpp`文件，并在`include`目录下创建您的服务头文件。

希望这可以帮助您将程序封装成service。
