ubuntu 编译 openMVS

主要记录ubuntu16.04下编译openMVS的问题。
主要是按照官网的教程，Linux compilation进行编译。

遇到的两个问题：
1、git clone ceres库的时候，克隆不了，官网命令如下：
git clone https://ceres-solver.googlesource.com/ceres-solver ceres-solver
因为这个项目要从google git下克隆，然后单纯的git没法下下来，就进入网页端下载了master分支的ceres，并解压缩到ceres-solver/里。

2、在make -j2， openMVS的时候，出现了下面的错误

错误原因：
网上搜了搜，应该是因为我装了anaconda3，并且在~/.bashrc里加了anaconda3/lib到LD_LIBRARY_PATH环境变量的原因。

解决方法：
参考链接：https://blog.csdn.net/u014734886/article/details/93029349

按照链接里把/usr/lib/x86_64-linux-gnu放在LD_LIBRARY_PATH环境变量里（如上图），解决了
/usr/bin/cmake: /home/ar443/anaconda3/lib/libcurl.so.4: no version information available (required by /usr/bin/cmake)问题，最后变成了这样。

然后
按照链接里的终极大法：把anaconda3/lib下的libuuid库文件移走，命令如下图：
Note：我的是anaconda3，上面的命令里的路径要改一下。
然后就变成了

到此，openMVS就编译成功了，然后就可以去bin下面快乐的玩耍，了如下图所示。

但是在viewer还有点问题，如下图，但是感觉和上面一样移动libxxx库就好了，因为我没有要用到viewer的需求，就不接着弄了。
