Fix the generated cmake-config file to look for the used Abseil-cpp config files providing the needed targets. When using Abseil from system (or locally installed and set via `absl_DIR`) the used targets like `absl::log` need to be made available in downstream projects using `ceres-solver`. For system packages with no `absl_VERSION` info check for the required target `absl::absl_vlog_is_on`, just like we do in `CMakeLists.txt`. Error on installation/export of "no-absl-VERSION" as we can't check version mismatches. When using `abseil-cpp` as submodule the abseil-configs are added to the install target as well. Use these config files to make the needed Abseil targets available. In the submodule case extract the `absl_VERSION` variable from its `CMakeLists.txt` file for us to check against in the generated cmake-config-file.

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