安装相关软件包 OpenCV eigen pangolin pcl

版本： ubuntu18.04 OpenCV

sudo apt install  build-essential
sudo apt install cmake git libgtk2.0-dev pkg-config libavcodec-dev libavformat-dev libswscale-dev  
sudo apt install python-dev python-numpy libtbb2 libtbb-dev libjpeg-dev libpng-dev libtiff-dev libjasper-dev libdc1394-22-dev

第三行中，可能会出现 无法定位软件包libjasper-dev 的错误提示

sudo add-apt-repository "deb http://security.ubuntu.com/ubuntu xenial-security main"
sudo apt update
sudo apt upgrade
sudo apt install libjasper1 libjasper-dev

其中 libjasper1 是 libjasper-dev 的依赖包

2.获取Source

接下来获取 OpenCV 的 source 文件，直接到官网下载：https://opencv.org/releases/

这里我们用的是3.4版本

3.用 CMake 从 Source 构建 OpenCV

进入解压出来的OpenCV-3.4.x文件夹，创建一个新文件夹，创建 build文件

启动终端，输入

cmake -D CMAKE_BUILD_TYPE=Release -D CMAKE_INSTALL_PREFIX=/usr/local .. 

之后

sudo make

再之后

sudo make install 

CMakeLists.txt调用格式

find_package( OpenCV REQUIRED )
include_directories( ${OpenCV_INCLUDE_DIRS} )
target_link_libraries( xxxx ${OpenCV_LIBS} )
