Ensure build paths for dependencies are searched in FindPackage(Ceres)
- Append to hint locations used by FindPackage scripts for public
dependencies (glog & Eigen) the locations of the dependencies when
Ceres was built.
- This means that the user should not have to supply them again when
using find_package(Ceres) even if they are installed in a
non-standard location.
