- Update FindSuiteSparse to use FindTBB.cmake to find TBB.
- Fix logic handling of TBB=ON if TBB is not found to continue with
build after disabling TBB rather than throwing a fatal error.
- Use TBB_LIBRARIES instead of TBB_tbb_LIBRARY as a Ceres dependency,
the former also includes the TBB malloc library.
- Add warning message about GPL licensing if TBB version < 2017.
- Add ‘TBB’ & ‘Mulithreading’ component options to find_package(Ceres),
where ‘Mulithreading’ is equivalent to ‘TBB’ || ‘OpenMP’.

- Also enable EIGENSPARSE option by default as LGPL licensing
implications are less severe that SuiteSparse’s GPL implications which
is enabled by default.

There are platforms where OpenMP is not available. This
patch adds support for Intel Threading Building Blocks (TBB)
as an alternative threading backend.

- Previously the LAPACK option meant would Ceres link against LAPACK,
whether directly or indirectly via SuiteSparse (if SUITESPARSE=ON),
as such if LAPACK=OFF, the use of SuiteSparse was disabled, even if
it was found.
- To support the use-case of using a limited LAPACK implementation that
satisfies SuiteSparse’s requirements, but potentially not Ceres’ we
now adopt the more conventional terminology whereby the LAPACK option
refers only to whether Ceres itself will directly call LAPACK
routines, not whether it or any of its dependencies will.
- This means that the LAPACK and SUITESPARSE options are now
independent.
- Also unnecessary calls to find_package(BLAS), as find_package(LAPACK)
already searches for BLAS, and appends the resulting libraries to
LAPACK_LIBRARIES if they are found.
