0 编译环境
所需软件包及其版本
Qt5.9.6 msvc2015_64
VS2015
VTK 8.0.0 https://gitlab.kitware.com/vtk/vtk/tree/v8.0.0
PCL1.8.1 https://github.com/PointCloudLibrary/pcl/releases/tag/pcl-1.8.1
PCL-1.8.1-AllInOne-msvc2015-win64
cmake3.11.3 https://cmake.org/download/
1 前期准备
下载上述软件。
安装vs2015。
安装Qt5.9.6。
在VS2015扩展和更新中安装 Qt Visual Studio Tools。
2 在VS中安装PCL 1.8.1
PCL1.8.1下载.jpg
需要下载AllinOne和pdb两个包，我选择的是2015-win64版本。
自动在环境变量中添加PCL路径
PCL安装路径，网上说路径不能有空格。
将OpenNI2安装到PCL1.8.1\3rdParty\OpenNI2\目录，这是为了便于管理，可以选择自己喜欢的目录。修改也很方便，OpenNI2可以单独卸载安装。安装包就在PCL1.8.1\3rdParty\OpenNI2\目录。
2.2 编译tutorials
tutorials的路径在C:\PCL1.8.1\share\doc\pcl-1.8\tutorials\sources下。
所以首先用cmake进行配置，配置完成后，DAVID和PKG都提示找不到，如果不用就不管。我用到了RSSDK，所以加上了。
选择Generate，我选择的是Visual Studio 14 2015 Win64。
选择open project后，vs2015就会打开工程。直接生成，结束后会有一些错误，比如：
无法打开 源 文件 "pcl/io/openni_grabber.h"
2.3 运行PCL VS2015 demo
将pcl_visualizer_demo设为启动项。
设置命行参数为-c，
启动后看到如图效果。说明PCL库+VS已经OK。
3 在Qt中安装PCL 1.8.1
在Qt中安装PCL1.8.1必须先做到本文第2部分。
PCL1.8.1中集成了VTK8.0.0，但是和VTK官网的8.0.0在个别文件上有差异，这就导致了在QT工程中集成PCL会出一些问题，比如找不到函数，debug和release版本冲突等问题。一些常用的解决办法，如
include <vtkAutoInit.h>
VTK_MODULE_INIT(vtkRenderingOpenGL2);
VTK_MODULE_INIT(vtkInteractionStyle);
并不能解决这些问题，所以解决思路是用VTK官方提供的8.0.0替换掉PCL_AllinOne中的VTK。
3.1 下载并编译VTK8.0.0
点击下载已经编译好的VTK8.0.0库，可跳过3.1。https://download.csdn.net/download/jepco1/10489293
具体方法参考博客中另一篇帖子VTK8.1.1的编译方法。
同样需要编译debug和release版本。
编译的结果被放在install目录和build目录。
build目录在这里被指定。
install目录在这里被指定。
3.2 安装及配置
生成的编译结果和路径如表
include VTK_INSTALLL\include
lib VTK_build\lib
dll VTK_build\bin
plugin VTK_build\bin\Release\QVTKWidgetPlugin.dll
lib和dll都是区分debug和release的。
替换bin
将VTK_build\bin的debug和release文件夹复制到C:\PCL1.8.1\3rdParty\VTK\bin
替换lib
将VTK_build\lib的debug和release复制到C:\PCL1.8.1\3rdParty\VTK\lib
替换include
删除C:\PCL1.8.1\3rdParty\VTK\include目录的文件。
将VTK_Install\include目录的内容复制到C:\PCL1.8.1\3rdParty\VTK\include
安装plugin
VTK_build\bin\Release\QVTKWidgetPlugin.dll文件复制到qt的插件目录
3.3 设置环境变量
PCL自动添加的环境变量不一定正确完整，建议检查一下。
PCL_ROOT存在且位置正确。
4个bin文件存在，且位置正确。
注意：这里要将VTK\bin路径删除。因为PCL中的VTK dll没有区分release和debug版本。需要通过编译器的环境配置，通过路径区分版本，这里如果包含了VTK\bin路径就会形成干扰。
4 编译qt_visualizer
4.1 打开qt_visualizer
位于C:\PCL1.8.1\share\doc\pcl-1.8\tutorials\sources\qt_visualizer
4.2 配置环境变量（dll路径）
debug
PATH=(PATH)(QTDIR)\bin(PCL_ROOT)\3rdParty\VTK\bin\release
4.3 配置include（.h路径）
debug|release
.\GeneratedFiles$(ConfigurationName);.\GeneratedFiles;.;(QTDIR)\include\QtWidgets;(QTDIR)\include\QtANGLE;(QTDIR)\mkspecs\win32-msvc;(PCL_ROOT)\include\pcl-1.8\pcl;(PCL_ROOT)\3rdParty\Eigen\eigen3;(PCL_ROOT)\3rdParty\OpenNI2\Include\Win32;(PCL_ROOT)\3rdParty\VTK\include\vtk-8.0;%(AdditionalIncludeDirectories)
4.4 配置lib路径
debug
(PCL_ROOT)\lib;(PCL_ROOT)\3rdParty\Boost\lib;(PCL_ROOT)\3rdParty\VTK\lib\debug;(QTDIR)\lib;(PCL_ROOT)\3rdParty\FLANN\lib;(PCL_ROOT)\3rdParty\Qhull\lib;(PCL_ROOT)\3rdParty\OpenNI2\Lib;%(AdditionalLibraryDirectories)
4.5 配置lib文件
debug
qtmaind.lib
shell32.lib
Qt5Widgetsd.lib
Qt5Guid.lib
Qt5Cored.lib
pcl_common_debug.lib
pcl_features_debug.lib
pcl_filters_debug.lib
