Idea to improve the installation step in the README.md

[ferreram]

Hi, Thanks a lot for your library!

In order to help people use it easily, I think you could add the following indications in the installation step:

• Required: apt-get install libdw-dev
• In code_utils: in mat_io_test.cpp and sumpixel_test.cpp => change ' #include "backward.hpp" ' into ' #include "code_utils/backward.hpp" '

Cheers

@gaowenliang I had some more issues during installation, and here how is I fixed it.

Ceres solver is required. Steps to install Ceres:

sudo apt-get install libgoogle-glog-dev
sudo apt-get install libatlas-base-dev
sudo apt-get install libeigen3-dev

Download the following file:

http://ceres-solver.org/ceres-solver-1.14.0.tar.gz

Execute:

tar zxf ceres-solver-1.14.0.tar.gz
mkdir ceres-bin
cd ceres-bin
cmake ../ceres-solver-1.14.0
make -j3
make install

Also, in sumpixel_test.cpp, I had to change

#include "backward.hpp"

to

#include "code_utils/backward.hpp"

Thanks.
