三维重建openMVS-Gpu cuda11.4 win10 vs2019 cmake3.23.1 vcpkg编译安装
本机环境如下：
| 名称 | 版本 |
|---|---|
| cuda | 11.4 |
| vs2019 | |
| cmake | 3.23.1 |
| boost | 1.79.0 |
| cgal | 5.4 |
| glew | 2.2.0 |
| eigen3 | 3.4.0 |
| glew | 2.2.0 |
| glfw3 | 3.3.7 |
| gmp | 6.2.1 |
| mpfr | 4.1.0 |
| opencv4 | 4.5.5 |
| zlib | 1.2.12 |
OpenMVS官方给的安装步骤如下：
#Make a toplevel directory for deps & build & src somewhere:
mkdir OpenMVS
cd OpenMVS
#Get and install dependencies using vcpkg;
#choose the desired triplet, like "x64-windows", by setting the VCPKG_DEFAULT_TRIPLET environment variable or by specifying it after each package:
vcpkg install zlib boost-iostreams boost-program-options boost-system boost-serialization eigen3 cgal[core] opencv glew glfw3
#Get VCGLib (Required):
git clone https://github.com/cdcseacave/VCG.git
#Get and unpack OpenMVS in OpenMVS/src:
git clone https://github.com/cdcseacave/openMVS.git src
#Make build directory:
mkdir build
cd build
#Run CMake, where VCPKG_ROOT environment variable points to the root of vcpkg installation:
cmake . ..\src -G "Visual Studio 15 2017 Win64" -DCMAKE_TOOLCHAIN_FILE=%VCPKG_ROOT%\scripts\buildsystems\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows -DVCG_ROOT="..\VCG"
#Open the solution in MSVC and build it
1.用vcpkg安装并编译外部依赖
VCPKG安装
下载vcpkg库：https://gitee.com/mirrors/vcpkg.git
然后运行:：.\vcpkg\bootstrap-vcpkg.bat
运行完之后把vcpkg添加到环境变量即可。
用vcpkg安装包
vcpkg install zlib:x64-windows boost:x64-windows eigen3:x64-windows cgal:x64-windows opencv:x64-windows glew:x64-windows glfw3:x64-windows
下载的包在yourpath/vcpkg/installed中。
运行中可能会提示cmake、boost版本错误需要更新，脚本会自动下载，但可能因为网络问题卡住，比如：
download过程中可能像上图一样卡住不动，可以把该步骤链接地址复制下来用freedownload manager去下载，有的包需要，有的不需要，如果超时就试试开启或者关闭工具，最后总能下载好。记得要按照其提示的名字进行重复名并放到vcpkg/downloads目录下，这样脚本才能检测到。下载完之后重新运行安装脚本即可。如果实在没有条件可以私信帮你下载，可能回复有延迟。
如果git出现time out尝试以下命令：
git config --global --unset http.proxy
vcpkg编译python报错：
error: building python3:x64-windows failed with: BUILD_FAILED
Please ensure you‘re using the latest port files with 'git pull' and 'vcpkg update'
参考了一篇博客，查看E:\vcpkg-master\ports\python3\portfile.cmake，里面有说明关于win sdk的问题。
# The Windows 11 SDK has a problem that causes it to error on the resource files, so we patch that.
if(VCPKG_TARGET_IS_WINDOWS OR VCPKG_TARGET_IS_UWP)
vcpkg_get_windows_sdk(WINSDK_VERSION)
if("${WINSDK_VERSION}" VERSION_GREATER_EQUAL "10.0.22000")
list(APPEND PATCHES "0007-workaround-windows-11-sdk-rc-compiler-error.patch")
endif()
endif()
这里是对win-sdk有限制，需要10.0.22000版本，我尝试过把这个修改成其他版本，但并不行，要求版本的WIN-SDK下载链接如下：WIN-SDK10.0.22000下载链接：https://developer.microsoft.com/en-us/windows/downloads/windows-sdk/
2.cmake部分：
首先要检查cmakelist中OpenMVS_USE_CUDA是否为ON，防止做无用功。
按照官网操作：
cmake . ../src -G "Visual Studio 16 2019" -DCMAKE_TOOLCHAIN_FILE=E:/vcpkg/scripts/buildsystems/vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows -DVCG_ROOT="../VCG"
报错：
看不出来哪里有问题，下面在cmake（版本：3.23.1 April13 release）中进行配置。
配置过程中关键库（CGAL/GMP/MPFR/EIGEN/）报错：
报错a：

在相应位置也没有找到MVS.lib，而只有common.lib\math.lib\io.lib。因此尝试先生成MVS，选择MVS为启动项然后生成，报错如下

解决cuda相关问题：这里看到cuda官网给出的一段解释是这是cuda11.3存在bug，已经在后续的版本进行了修正，如果你在一开始就用cuda11.4那么应该不存在此问题，可以跳过。
在解决cuda报错后重新生成MVS，仍然存在报错，说明在cmake步骤存在问题。仔细看一下cmake中输出的信息,里面有一段关于MVS的warning：

这里在cmake中修改相应的库路径后依然无法解决。开始怀疑是不是boost和cmake的版本问题导致的cmake检索不到。因此长袖修改boost版本。事实证明并不是版本问题，所作操作如下。
================================================================
问题步骤，更改boost版本这一步，在后面步骤中发现此该步无效，就当学习了
cmake需要用boost发布版本之后的，这里3.23时april13 boost1.79也是april13，因此将boost改成了1.78版本，这里给出一个下载地址：
Boost下载地址：https://boostorg.jfrog.io/ui/native/main/release/1.68.0/source/
下载完之后使用vs2019进行编译，编译过程参考：Boost编译教程：https://blog.csdn.net/fenghaiyang198848/article/details/120017165
这里再简单记录一下：
1.运行Developer Command Prompt for VS 2019；
2.进入解压目录；
3.bootstrap msvc；
4.编译并安装b2 install --build-type=complete threading=multi link=shared address-model=64 toolset=msvc-16.0
5.编译完成后自动存放在C:\Boost。
msvc版本对应关系如下，推荐msvc2019，如果不一样可能需要下载不同版本的包：
| VC版本 | VS版本 | MSVC版本 |
|---|---|---|
| VC14.0 | VS2015 | v130 |
| VC15.0 | VS2017 | v141 |
| VC16.0 | VS2019 | v142 |
| VC17.0 | VS2022 | v143 |
下载完后在cmake中配置boost的include和library路径，依然有同样的错误。
CMake Error at E:/cmake/share/cmake-3.23/Modules/FindPackageHandleStandardArgs.cmake:230 (message):
Could NOT find Boost (missing: iostreams program_options system
serialization) (found version "1.77.0")
Call Stack (most recent call first):

E:/cmake/share/cmake-3.23/Modules/FindBoost.cmake:2375 (find_package_handle_standard_args)
CMakeLists.txt:168 (FIND_PACKAGE)
================================================================
问题解决：在Cmake中选中Boost_Debug可以输出cmake在查询lib时的所用路径信息，发现其搜索路径不匹配。因此需要添加变量BOOST_LIBRARYDIR，到你的lib路径，进去之后要看搜索名字与你的实际lib名字是否对应，并做相应修改。
可能会提示GLEW、GLFW3未找到并continuing without it，这里最好不要让他跳过，在cmake中选择好vcpkg下载后的对应路径继续configure、generate。
3.OpenMVS在vs2019中生成可执行文件：
用vs2019打开OpenMVS.sln，将MVS设为启动项进行生成。生成成功后，把app中的DensifyPointCloudInterfaceCOLMAP依次生成为可执行程序。
sln在生成app过程中中报错：
错误1
LNK1104 无法打开文件“libboost_serialization-vc142-mt-gd-x32-1_74.lib” DensifyPointCloud
类似的错误可以通过修改lib文件名解决。
错误2
严重性代码说明项目文件行禁止显示状态错误 LNK1104 无法打开文件“libboost_zlib-vc142-mt-x64-1_77.lib” DensifyPointCloud E:\openMVS-develop\build\apps\DensifyPointCloud\LINK 1
该错误无论怎么修改文件名和配置路径都无效，可能因为zlib是在vcpkg中自动编译的，boost是自己用msvc2019编译的，所以可能是在编译过程中某些参数不对所以存在版本不匹配的问题，这里又切回了原来vcpkg下载的boost，配置过程相同，重新configure、generate成功，再重新打开OpenMVS.sln进行生成。
总结步骤如下：
1.mkdir openmvs cd openmvs
2.Github下载OpenMVS-develop：[https://github.com/cdcseacave/openMVS/tree/develop](https://github.com/cdcseacave/openMVS/tree/develop)
建议下载OpenMVS-develop，该版本是持续更新的一版，减少出错可能，因为里边有外部依赖项，下载龟速，这里提供百度云链接：百度云链接：https://pan.baidu.com/s/1KVwT1ZPpxq-8V8zTQ72Btw，提取码：39hc
3.用vcpkg编译依赖包
vcpkg install zlib:x64-windows boost:x64-windows eigen3:x64-windows cgal:x64-windows opencv:x64-windows glew:x64-windows glfw3:x64-windows
安装过程中的问题看上面的描述
4.下载VCG
git clone https://github.com/cdcseacave/VCG.git
5.cmake
添加变量BOOST_LIBRARYDIR = yourpath/vcpkg/installed/x64-windows/lib，如果有其他依赖项需要配置，参考上面的过程进行confgure。
6.生成可执行文件
用vs2019打开OpenMVS.sln，以MVS为启动项生成lib，然后按照需求依次生成app中的项目（DensifyPointCloud、InterfaceCOLMAP、InterfaceMetashape、ReconstructMesh、RefineMesh、TextureMesh、Viewer）即可。
存在少部分报错信息忘记截图，但所遇到的关键要解决的问题已经总结如上。
