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.
