undefined reference to `ceres::Solve(ceres::Solver::Options const&, ceres::Problem*,

问题描述：
软件安装编译时，出现以下问题，是ceres库和glog库有问题

undefined reference to `google::LogMessageFatal::LogMessageFatal(char const*, int)'
../../../Linux-x86_64/libaliceVision_multiview.so.2.2: undefined reference to `google::base::CheckOpMessageBuilder::CheckOpMessageBuilder(char const*)'

于是安装gflags，glog，suitsparse，安装后重新编译发现还是有问题，于是写了一个简单的测试ceres库的代码，可以正常cmake和编译，但执行程序时有以下报错

./ceres_stitchedimage: error while loading shared libraries: libgflags.so.2.2: cannot open shared object file: No such file or directory

加载不到动态库，在电脑内搜索该库，发现并没有该动态库，只有gflag的静态库，于是重新编译安装gflags。

解决方法：
编译安装gflags，降低ceres版本即可编译成功
