PCL（Point Cloud Library）有很多版本，很多博主只是簡單給一個連接，但是軟件會有更新的版本推出，所以教給大家怎樣能夠找到自己想要的版本。
對於剛剛接觸PCL的人來說，在Windows下配置PCL並不是一件輕鬆的事情，我把自己經歷的坑總結、分享出來，希望一起學習，共同進步。
PCL庫：
尋找資源並下載PCL庫：http://pointclouds.org ，這是PCL的官網，下載速度還比較快，建議在官網下載。點擊主頁的Dev Zone。（嫌麻煩的小夥伴可以我的雲盤下載，版本：PCL-1.8.1-AllInOne-msvc2017-win64.exe、pcl-1.8.1-pdb-msvc2017-win64.zip以及後面例子要用的rabbit.pcd文件。鏈接：https://pan.baidu.com/s/1-1rTxA69xG73BbCk17GDjQ，提取碼：98st ）
點擊連接後轉入GitHub頁面，點擊Releases，點擊tags，找到自己想要的版本，點擊進去，拉倒頁面最下面。（我選擇的1.8.1版本，小夥伴們可根據自己的需求選擇不同版本）
下載完成後，開始安裝。安裝過程中特別需要說明的地方會截圖出來，未做截圖說明的，默認即可。
在圖六中一定勾選上Add PCL to system PATH for all users。
圖六
修改安裝路徑到你想要的位置（默認的是C盤）
安裝過程中，會彈出OpenNI的安裝程序，更改安裝路徑爲你安裝的PCL路徑下的3rdParty文件夾下的OpenNI2文件夾中。
拷貝之前下載的pcl-1.8.1-pdb-msvc2017-win64.zip裏面所有的內容（不要文件夾直接拷過去，只拷貝內容），到你PCL安裝路徑下的bin文件夾。
配置電腦環境變量
我的電腦右鍵-->屬性-->高級系統設置-->高級-->環境變量-->系統變量-->Path-->編輯-->新建
D:\PCL 1.8.1\bin
D:\PCL 1.8.1\3rdParty\FLANN\bin
D:\PCL 1.8.1\3rdParty\Qhull\bin
D:\PCL 1.8.1\3rdParty\VTK\bin
D:\PCL 1.8.1\3rdParty\OpenNI2\Tools
配置VS2017(這部分是重點，需要格外注意)
打開VS新建一個控制檯程序。在解決方案管理器裏找到你新建的項目，右鍵點屬性，彈出屬性頁窗口。
1、調試 -->環境，添加內容如下：
path=D:\PCL 1.8.1\bin;
2、C/C++-->預處理器-->預處理器定義，添加上如下內容：
_CRT_SECURE_NO_WARNINGS
_SCL_SECURE_NO_WARNINGS
3、VC++目錄-->包含目錄，添加如下內容：
D:\PCL 1.8.1\include\pcl-1.8;
D:\PCL 1.8.1\3rdParty\Boost\include\boost-1_64;
D:\PCL 1.8.1\3rdParty\Eigen\eigen3;
D:\PCL 1.8.1\3rdParty\FLANN\include;
D:\PCL 1.8.1\3rdParty\Qhull\include;
D:\PCL 1.8.1\3rdParty\VTK\include\vtk-8.0;
D:\PCL 1.8.1\3rdParty\OpenNI2\Include
4、VC++目錄-->庫目錄，添加如下內容
D:\PCL 1.8.1\lib;
D:\PCL 1.8.1\3rdParty\Boost\lib;
D:\PCL 1.8.1\3rdParty\FLANN\lib;
D:\PCL 1.8.1\3rdParty\Qhull\lib;
D:\PCL 1.8.1\3rdParty\VTK\lib;
D:\PCL 1.8.1\3rdParty\OpenNI2\Lib;
5、鏈接器-->輸入-->附加依賴項，添加以下內容（分Debug版本和Release版本），有很多小夥伴到這一步就好使了，可以直接運行後面的例子，如果編譯有錯誤，繼續配置：

註釋：提取文件夾中.lib文件名總是會出現錯誤，下面是自己動手豐衣足食型：
例：提取D:\PCL 1.8.1\3rdParty\VTK\lib下的所有靜態鏈接庫文件名並存儲至文本.txt，方法如下：
1、win+r
2、輸入：cmd回車
3、輸入：cd /d D:\PCL 1.8.1\3rdParty\VTK\lib 回車
4、輸入：dir /b *.lib *>0.txt 回車
6、配置屬性-->調試-->環境，設置的內容如下：
PATH=$(PCL_ROOT)bin;$(PCL_ROOT)3rdPartyFLANNbin;$(PCL_ROOT)3rdPartyVTKbin;$(PCL_ROOT)Qhullbin;$(PCL_ROOT)3rdPartyOpenNI2Tools;$(PATH)
例子：
rabbit.pcd文件在前面的網盤中，代碼如下：
#include<pcl/visualization/cloud_viewer.h>
#include<iostream>
#include<pcl/io/io.h>
#include<pcl/io/pcd_io.h>
#include<pcl/io/ply_io.h>
