Fix custom Eigen on macos (EIGEN_INCLUDE_DIR_HINTS)

In ceres' CMakeLists.txt a workaround for custom homebrew locations
sets CMAKE_PREFIX_PATH to the homebrew install path. This overrides
explicit requests for custom locations for third-party dependencies,
in particular for Eigen with EIGEN_INCLUDE_DIR_HINTS.

This commit introduces a workaround to make EIGEN_INCLUDE_DIR_HINTS
work on macos by ignoring CMAKE_PREFIX_PATH in that case.

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.
