如何编译点云库（PCL）带实例（Ubuntu）？
How to compile Point Cloud Library (PCL) with examples (Ubuntu)?
我正在使用 Ubuntu 18.04，但是对于任何最近的 Linux 发行版，这个问题应该几乎相同。
基于此post：
How to install Point Cloud Library v1.8 on Ubuntu 16
我正在尝试从源代码构建 Point Cloud Library，如下所示：
安装各种包：
sudo apt-get -y install g++ cmake cmake-gui doxygen mpi-default-dev openmpi-bin openmpi-common
sudo apt-get -y install libusb-1.0-0-dev libqhull* libusb-dev libgtest-dev
sudo apt-get -y install git-core freeglut3-dev pkg-config build-essential libxmu-dev libxi-dev
sudo apt-get -y install libphonon-dev libphonon-dev phonon-backend-gstreamer
sudo apt-get -y install phonon-backend-vlc graphviz mono-complete
sudo apt-get -y install qt5-default
sudo apt-get -y install libflann-dev
sudo apt-get -y install libflann1.9
sudo apt-get -y install libboost-dev
sudo apt-get -y install libeigen3-dev
编译安装VTK 8.1.1:
cd ~/Downloads
wget http://www.vtk.org/files/release/8.1/VTK-8.1.1.tar.gz
tar -zxvf VTK-8.1.1.tar.gz
cd VTK-8.1.1
mkdir build
cd build
cmake ..
make
sudo make install
编译安装PCL1.8.1
cd ~/Downloads
wget https://github.com/PointCloudLibrary/pcl/archive/pcl-1.8.1.tar.gz
tar -zxvf pcl-1.8.1.tar.gz
cd pcl-pcl-1.8.1
mkdir build
cd build
cmake ..
make
sudo make install
运行 一个 ldconfig
sudo ldconfig
效果很好，但是 PCL 示例未设置为默认编译，我真的很希望能够 运行 这些示例。参考这个 post:
Cannot compile pcl examples with cmake
我按照上面的方法进行，只是在去皮后PCL，我打开了文件
~/Downloads/pcl-pcl-1.8.1/CMakeLists.txt
我为 example 按了 Ctrl-F 并找到了以下几行：
### ---[ Set up for examples
#include("${PCL_SOURCE_DIR}/cmake/pcl_examples.cmake")
接下来我删除了这两行第二行开头的注释字符#，所以现在我有：
### ---[ Set up for examples
include("${PCL_SOURCE_DIR}/cmake/pcl_examples.cmake")
继续执行上述步骤，当我执行 cmake .. 现在我得到：

在您的 cmake 命令中，请添加 -DBUILD_examples=ON 作为启用示例的选项。
