二、编译MVS
Build instructions
Required tools:
- CMake
- git
- C/C++ compiler like Visual Studio or GCC
Windows compilation
Visual Studio 2008 or newer are supported. Please note that the development is done mainly on Windows, so this platform build is well tested. The latest pre-built binaries for fast testing can be download from here. Visual Studio 2017 and dependencies automation tool vcpkg are used in this example.
#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 eigen3 ceres opencv cgal 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通过vcpkg编译好我们需要的的库：
.\vcpkg.exe install zlib:x64-windows boost:x64-windows eigen3:x64-windows ceres:x64-windows opencv:x64-windows cgal:x64-windows glew:x64-windows glfw3:x64-windows
然后新建OpenMVS文件夹
在里面git
git clone https://github.com/cdcseacave/VCG.gitgit clone https://github.com/cdcseacave/openMVS.git src然后再OpenMVS文件夹下新建一个build
打开build
输入命令：
cmake . ..\src -G "Visual Studio 15 2017 Win64" -DCMAKE_TOOLCHAIN_FILE=G:\vcpkg\scripts\buildsystems\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows -DVCG_ROOT=G:\VS2017code\OpenMVS\VCG
打开sln工程文件
会出现错误，因为由于CGAL版本过高，和OpenMVS不一致导致

========== Build: 5 succeeded, 7 failed, 0 up-to-date, 6 skipped ==========这里我们列出以下我们的版本：
CGAL 4.13.2
在一个issues中有同样的问题：
https://github.com/cdcseacave/openMVS/issues/374
最后的答案是：
卸载现有的CGAL，并重新安装CGAL 4.7
.\vcpkg.exe remove cgal:x64-windows
在vcpkg文件夹下找到CGAL
G:\vcpkg\ports\cgal
打开.cmake文件
这里我们主要修改REF和SHA512即可
vcpkg_from_github(
OUT_SOURCE_PATH SOURCE_PATH
REPO CGAL/cgal
#REF releases/CGAL-4.13
REF releases/CGAL-4.7
#SHA512 3a12d7f567487c282928a162a47737c41c22258556ca0083b9cf492fc8f0a7c334b491b14dbfd6a62e71feeeb1b4995769c13a604e0882548f21c41b996d4eaf
SHA512 A1F9079D056CA162CC0B181CBBAD06B44CEDE2B835861EF76BF86B7A01F8ABF1C0E36E6129249CF8A63EE2C4383059B252F4E28251317C9812F63B80CE0DE4A5
HEAD_REF master
)
然后输入
.\vcpkg.exe install cgal:x64-windows
这里使用的是小写的hash
我们需要修改一下：
vcpkg_from_github(
OUT_SOURCE_PATH SOURCE_PATH
REPO CGAL/cgal
#REF releases/CGAL-4.13
REF releases/CGAL-4.7
#SHA512 3a12d7f567487c282928a162a47737c41c22258556ca0083b9cf492fc8f0a7c334b491b14dbfd6a62e71feeeb1b4995769c13a604e0882548f21c41b996d4eaf
#SHA512 A1F9079D056CA162CC0B181CBBAD06B44CEDE2B835861EF76BF86B7A01F8ABF1C0E36E6129249CF8A63EE2C4383059B252F4E28251317C9812F63B80CE0DE4A5
SHA512 a1f9079d056ca162cc0b181cbbad06b44cede2b835861ef76bf86b7a01f8abf1c0e36e6129249cf8a63ee2c4383059b252f4e28251317c9812f63b80ce0de4a5
HEAD_REF master
)然后把地址
G:\vcpkg\buildtrees\cgal
删除干净
又出现新的问题：
可能依赖的问题，我们放弃这种方式
把所有的CGAL信息全部换回原来的版本
编译CGAL4.13
重新下载MVS的代码进行编译
这次我们下载其他版本的代码
顺便记录一下时间段
选择develop，这是会不停更新的代码分支
作者说已经在这个分支里面解决了错误
修改一下命令，重新编译：
cmake . ..\openMVS-develop -G "Visual Studio 15 2017 Win64" -DCMAKE_TOOLCHAIN_FILE=G:\vcpkg\scripts\buildsystems\vcpkg.cmake -DVCPKG_TARGET_TRIPLET=x64-windows -DVCG_ROOT=G:\VS2017code\OpenMVS\VCG
笔记：下面的和本主题无关
打开GitHub,找到CGAL4.7
https://github.com/CGAL/cgal/releases?after=releases%2FCGAL-4.8.2
