Require >= C++11 & CMake >= 3.5 when building Ceres.

- Removes CXX11 option, and all associate paraphernalia.  Ceres now
  requires a compiler with full >= C++11 support.  In MSVC terms this
  means >= 2013 Release 4.
- This deprecates the use of CERES_STD_UNORDERED_MAP and CERES_USE_CXX11
  as they will now always be defined.  They will be removed from the
  source in a future CL.
- For clients with CMake >= 3.8 we propagate via the exported/installed
  Ceres target the CXX version that was specified when Ceres was built.
  For versions < 3.8 (but >= 3.5) we specify the CXX features currently
  used in the Ceres public API.

Ceres Solver

Ceres Solver is an open source C++ library for modeling and solving large, complicated optimization problems. It is a feature rich, mature and performant library which has been used in production at Google since 2010. Ceres Solver can solve two kinds of problems.

  1. Non-linear Least Squares problems with bounds constraints.
  2. General unconstrained optimization problems.

Please see ceres-solver.org for more information.
