Ceres Solver for IOS Platform(armv7 arm64 x86_64)

This project is modified based on Ceres V2.0.0master branch(https://github.com/ceres-solver/ceres-solver)
But original version is not supported for all solver methods and you may only use DENSE_QR.
If you want to use some methods(ex.SPARSE_SCHUR) and you will find you can't use them. So, I build this project and make sure it is supported for suites-parse and you can use it for all solvers(ex.trust_region_strategy or SPARSE_NORMAL_CHOLESKY and so on)!

What I change

Firstly, I add Eigen3 source code and Accelerate.framework needed by libceres in 3rdParty path. Secondly, I modified both CMakeLists.txt under root path and internal/ceres to make sure cmake can find Eigen3 we added.

How to Compile

Follow command below, and you will get libceres.a for IOS platform(armv7 arm64 x86_64) in ios_build/
cd 3rdParty/eigen3
sh build.sh
and you will install Eigen3, and then
cd ../../ios_build
sh build.sh
Finally, libceres.a will be saved.
