一个“好看”的CMake管理应该是这样的：
├── CMakeLists.txt
├── main_class.cpp
├── main.cpp
├── model
│ ├── seg_0415.onnx
│ └── seg_0415.trt
├── Parser
│ ├── CMakeLists.txt
│ ├── data_frame_parser.cpp
│ └── data_frame_parser.h
├── RoadSeg
│ ├── CMakeLists.txt
│ ├── road_segmentation.cpp
│ └── road_segmentation.hpp
├── TCPClient
│ ├── CMakeLists.txt
│ ├── tcp_frame_client.cpp
│ └── tcp_frame_client.h
├── Test
│ ├── main_simple.cpp
│ ├── ptr_mat.cpp
│ └── test_main.cpp
└── Utils
├── CMakeLists.txt
├── logger.cpp
└── logger.h
具体而言，比如Parser下面的CMakeLists.txt：
find_package(OpenCV REQUIRED)
find_package(PCL REQUIRED)
# Find FFmpeg components
find_package(PkgConfig REQUIRED)
pkg_check_modules(AVCODEC REQUIRED libavcodec)
pkg_check_modules(AVFORMAT REQUIRED libavformat)
pkg_check_modules(SWSCALE REQUIRED libswscale)
pkg_check_modules(AVUTIL REQUIRED libavutil)
include_directories(
${OpenCV_INCLUDE_DIRS}
${PCL_INCLUDE_DIRS}
${AVCODEC_INCLUDE_DIRS}
${AVFORMAT_INCLUDE_DIRS}
${SWSCALE_INCLUDE_DIRS}
${AVUTIL_INCLUDE_DIRS}
/usr/include
${CMAKE_SOURCE_DIR}/Utils
)
# 添加Parser库
add_library(Parser SHARED
data_frame_parser.cpp
data_frame_parser.h
)
target_include_directories(Parser PUBLIC
${CMAKE_CURRENT_SOURCE_DIR}
)
target_link_libraries(Parser
${AVCODEC_LIBRARIES}
${AVFORMAT_LIBRARIES}
${SWSCALE_LIBRARIES}
${AVUTIL_LIBRARIES}
${OpenCV_LIBS}
${PCL_LIBRARIES}
lz4
Utils
)
而main函数的CMakeLists.txt就可以很简洁了:
cmake_minimum_required(VERSION 3.10)
project(DataFrameParser)
set(CMAKE_CXX_STANDARD 20)
set(CMAKE_CXX_STANDARD_REQUIRED True)
option(BUILD_SHARED_LIBS "Build libraries as shared libraries" ON)
# 添加子目录
add_subdirectory(Utils)
add_subdirectory(Parser)
add_subdirectory(TCPClient)
add_subdirectory(AI)
add_subdirectory(RoadSeg)
add_executable(DataFrameParser main_class.cpp)
target_link_libraries(DataFrameParser
Parser
TCPClient
AI4FS
RoadSeg
)
