## Declare ROS messages, services and actions ##
################################################## To declare and build messages, services or actions from within this
## package, follow these steps:
## * Let MSG_DEP_SET be the set of packages whose message types you use in
## your messages/services/actions (e.g. std_msgs, actionlib_msgs, ...).
## * In the file package.xml:
## * add a build_depend tag for "message_generation"
## * add a build_depend and a exec_depend tag for each package in MSG_DEP_SET
## * If MSG_DEP_SET isn't empty the following dependency has been pulled in
## but can be declared for certainty nonetheless:
## * add a exec_depend tag for "message_runtime"
## * In this file (CMakeLists.txt):
## * add "message_generation" and every package in MSG_DEP_SET to
## find_package(catkin REQUIRED COMPONENTS ...)
## * add "message_runtime" and every package in MSG_DEP_SET to
## catkin_package(CATKIN_DEPENDS ...)
## * uncomment the add_*_files sections below as needed
## and list every .msg/.srv/.action file to be processed
## * uncomment the generate_messages entry below
## * add every package in MSG_DEP_SET to generate_messages(DEPENDENCIES ...)## Generate messages in the 'msg' folder
# add_message_files(
# FILES

## Declare ROS dynamic reconfigure parameters ##
################################################## To declare and build dynamic reconfigure parameters within this

## * add "dynamic_reconfigure" to
## find_package(catkin REQUIRED COMPONENTS ...)

编译安装OpenCV依赖库
编译安装OpenCV环境
准备源码
# 编译工具
sudo apt-get install build-essential

sudo apt-get install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev libv4l-devsudo apt-get install libeigen3-dev libgflags-dev libgoogle-glog-dev
sudo apt-get install libsuitesparse-dev# 可选的

sudo apt-get install gtk-3.0-dev
sudo apt-get install libatlas-base-dev gfortran# 创建一个总目录存放两个子目录
mkdir -p ~/3rdparty/source/opencv_env
cd ~/3rdparty/source/opencv_env# 如果网络好就直接执行命令 , 总共700MB
git clone -b 3.4 https://gitee.com/mirrors/opencv.git
git clone -b 3.4 https://gitee.com/mirrors/opencv_contrib.git# 或者直接使用资料中下好的文件, 将这两个文件拷贝到opencv_env路径下
opencv-3.4.9.zip
opencv_contrib-3.4.9.tar.gz
# 使用tar -zxvf xxx.tar.gz 将上述两个文件进行解压准备编译依赖的文件
修改hosts文件
打开此链接：https://githubusercontent.com.ipaddress.com/raw.githubusercontent.com
将其中显示的IP Address地址复制到粘贴板，这里为199.232.96.133
编辑系统的hosts文件：
sudo gedit /etc/hosts把以下内容追加到末尾即可：
199.232.96.133 raw.githubusercontent.com注意，这里用到的ip地址是我在网站链接中获取的，可能与你获得的不同，注意区分，直接复制使用不保证有效！
提前释放要下载的内容到.cache目录
建议在直接将cache.tar.gz内容解压缩到opencv源码根目录下的.cache，即可避免由于需要在线下载会出现的问题。原因是执行cmake时候，脚本会自动到github的资源库raw.githubusercontent.com下载文件，而这个网站时不时的就被河蟹了（科学上网可以解决，但不是人人都有梯子的），所以这里提前把脚本要下载的准备到opencv源码根目录里的.cache里即可。注意此cache目前在opencv-3.4.9情况下可用，其他版本不保证。
cache.tar.gz的百度网盘链接: https://pan.baidu.com/s/1kZU1gakKLP-LjSxQ4DYw7g 提取码: 5fxk
然后执行以下命令，将其内容解压到opencv的源码根目录
tar -zxvf cache.tar.gz -C opencv此时，进入opencv目录，确认是否有.cache目录即可，注意这个是隐藏目录，文件浏览器里按 Ctrl+H 可以查看隐藏目录，命令行里可以输入ls -al查看
配置&编译&安装
# 进入Opencv目录
cd opencv-3.4.9
# 创建一个build目录
mkdir build
# 进入build目录
cd build# cmake编译配置：也可以自行使用cmake-gui配置# 一定要确保以下用到的OPENCV_EXTRA_MODULES_PATH参数路径在你那里是存在且正确的！！！# 注意末尾的两个点 .. 不能少，注意最后一个参数要根据你自己的路径来
cmake -D CMAKE_BUILD_TYPE=Release \-D BUILD_opencv_python2=OFF \-D BUILD_opencv_python3=ON \-D CMAKE_INSTALL_PREFIX=/usr/local \-D OPENCV_EXTRA_MODULES_PATH=~/3rdparty/source/opencv_env/opencv_contrib-3.4.9/modules ..# 或者用这个，可以编译安装一些Python和C++案例
cmake -D CMAKE_BUILD_TYPE=Release \-D BUILD_opencv_python2=OFF \-D BUILD_opencv_python3=ON \-D CMAKE_INSTALL_PREFIX=/usr/local \-D INSTALL_PYTHON_EXAMPLES=ON \-D OPENCV_EXTRA_MODULES_PATH=~/3rdparty/source/opencv_env/opencv_contrib-3.4.9/modules \-D BUILD_EXAMPLES=ON ..# 或者指定任意输出目录，例如我把OpenCV输出到 ~/3rdparty/OpenCV-3.4.9

make -j8# 编译成功之后, 再执行安装
# 这里会安装到刚刚CMAKE_INSTALL_PREFIX指定的路径，如果时使用的~/开头的用户目录，建议不要加sudo
sudo make install正常情况下，编译安装即到此完毕！
出现的问题
！！！！！！！！！！如果.cache目录已按照上述步骤自行解压过，则以下步骤可以省略！！！！！！！！！！！！！！！
- ippicv
由于是外国服务器原因，这里极大概率会出现下载错误，会提示ippicv_2019_lnx_intel64_general_20180723.tgz 下载失败!！解决方式如下
方式1：推荐
将ippicv_2019_lnx_intel64_general_20180723.tgz拷贝为opencv/.cache/ippicv/c0bd78adb4156bbf552c1dfe90599607-ippicv_2019_lnx_intel64_general_20180723.tgz即可
方式2：
# 打开终端，输入
gedit ~/opencv_env/opencv/3rdparty/ippicv/ippicv.cmake #就是这个文件的路径
# 将47行的
"https://raw.githubusercontent.com/opencv/opencv_3rdparty/${IPPICV_COMMIT}ippicv/"
# 改为步骤1中手动下载的文件的本地路径(也就是将网络下载的模式改为本地文件下载的模式):"file:///home/itheima/opencv_env/" #（仅供参考，根据自己的路径填写,ippicv所在的目录）
- face_landmark_model.dat
cmake过程中会到https://raw.githubusercontent.com/opencv/opencv_3rdparty/8afa57abc8229d611c4937165d20e2a2d9fc5a12/face_landmark_model.dat下载dat文件，这里提前准备好，就不需要联网下啦，进入opencv源码根目录，执行：
mkdir -p .cache/datacp face_landmark_model.dat .cache/data/7505c44ca4eb54b4ab1e4777cb96ac05-face_landmark_model.dat
