    Remove link-time optimisation (LTO).
    
    - On GCC 4.9+ although GCC supports LTO, it requires use of the
      non-default gcc-ar & gcc-ranlib.  Whilst we can ensure Ceres is
      compiled with these, doing so with GCC 4.9 causes multiple definition
      linker errors of static ints inside Eigen when compiling the tests
      and examples when they are not also built with LTO.
    - On OS X (Xcode 6 & 7) after the latest update to gtest, if LTO
      is used when compiling the tests (& examples), two tests fail
      due to typeinfo::operator== (things are fine if only Ceres itself is
      compiled with LTO).
    - This patch disables LTO for all compilers. It should be revisited when
      the performance is more stable across our supported compilers.

commit 89c40005bfceadb4163bd16b7464b3c2ce740daf
Author: Alex Stewart <alexs.mac@gmail.com>
Date:   Sun Sep 27 13:37:26 2015 +0100

    Only use LTO when compiling Ceres itself, not tests or examples.
    
    - If Ceres is built as a shared library, and LTO is enabled for Ceres
      and the tests, then type_info::operator==() incorrectly returns false
      in gtests' CheckedDowncastToActualType() in the following tests:
    -- levenberg_marquardt_strategy_test.
    -- gradient_checking_cost_function_test.
      on at least Xcode 6 & 7 as reported here:
      https://github.com/google/googletest/issues/595.
    - This does not appear to be a gtest issue, but is perhaps an LLVM bug
      or an RTTI shared library issue.  Either way, disabling the use of
      LTO when compiling the test application resolves the issue.
    - Allow LTO to be enabled for GCC, if it is supported.
    - Add CMake function to allow easy appending to target properties s/t
      Ceres library-specific compile flags can be iteratively constructed.

    Clean up iOS.cmake to use xcrun/xcodebuild & libtool.
    
    - Substantial cleanup of iOS.cmake to use xcrun & xcodebuild to
      determine the SDK & tool paths.
    - Use libtool -static to link libraries instead of ar + ranlib, which
      is not compatible with Xcode 7+, this change should be backwards
      compatible to at least Xcode 6.
    - Force locations of unordered_map & shared_ptr on iOS to work around
      check_cxx_source_compiles() running in a forked CMake instance without
      access to the variables (IOS_PLATFORM) defined by the user.
    - Minor CMake style updates.

    Remove FAQ about increasing inlining threshold for Clang.
    
    - Changing the inlining threshold for Clang as described has a minimal
      effect on user performance.
    - The problem that originally prompted the belief that it did was
      due to an erroneous CXX flag configuration (in user code).

    there is now a test for each solver configuration which
    uses the reference solution computed by the fixture.

    Revert increased inline threshold (iff Clang) to exported Ceres target.
    
    - Increasing the inline threshold results in very variable performance
      improvements, and could potentially confuse users if they are trying
      to set the inline threshold themselves.
    - As such, we no longer export our inline threshold configuration for
      Clang, but instead document how to change it in the FAQs.

    Improve performance of SPARSE_NORMAL_CHOLESKY + dynamic_sparsity
    
    The outer product computation logic in SparseNormalCholeskySolver
    does not work well with dynamic sparsity. The overhead of computing
    the sparsity pattern of the normal equations is only amortized if
    the sparsity is constant. If the sparsity can change from call to call
    SparseNormalCholeskySolver will actually be more expensive.
    
    For Eigen and for CXSparse we now explicitly compute the normal
    equations using their respective matrix-matrix product routines and solve.

    Add increased inline threshold (iff Clang) to exported Ceres target.
    
    - When compiled with Clang, Ceres and all of the examples are compiled
      with an increased inlining-threshold, as the default value can result
      in poor Eigen performance.
    - Previously, client code using Ceres would typically not use an
      increased inlining-threshold (unless the user has specifically added
      it themselves).  However, increasing the inlining threshold can result
      in significant performance improvements in auto-diffed CostFunctions.
    - This patch adds the inlining-threshold flags to the interface flags
      for the Ceres CMake target s/t any client code using Ceres (via
      CMake), and compiled with Clang, will now be compiled with the same
      increased inlining threshold as used by Ceres itself.

    Adaptive numeric differentiation using Ridders' method.
    
    This method numerically computes function derivatives in different
    scales, extrapolating between intermediate results to conserve function
    evaluations. Adaptive differentiation is essential to produce accurate
    results for functions with noisy derivatives.
    
    Full changelist:
    -Created a new type of NumericDiffMethod (RIDDERS).
    -Implemented EvaluateRiddersJacobianColumn in NumericDiff.
    -Created unit tests with f(x) = x^2 + [random noise] and
     f(x) = exp(x).

    Build position independent code when compiling Ceres statically.
    
    - Previously, when Ceres was built as a static library we did not
      compile position independent code.  This means that the resulting
      static library could not be linked against shared libraries, but
      could be used by executables.
    - To enable the use of a static Ceres library by other shared libraries
      as reported in [1], the static library must be generated from
      position independent code (except on Windows, where PIC does not
      apply).

    Fix a bug in DetectStructure
    
    The logic for determing static/dynamic f-block size in
    DetectStructure was broken in a corner case, where the very first
    row block which was used to initialize the f_block_size contained
    more than one f blocks of varying sizes. The way the if block
    was structured, no iteration was performed on the remaining
    f-blocks and the loop failed to detect that the f-block size
    was actually changing.
    
    If in the remaining row blocks, there were no row blocks
    with varying f-block sizes, the function will erroneously
    return a static f-block size.
    
    Thanks to Johannes Schonberger for providing a reproduction for this
    rather tricky corner case.

    Fix a bug in the Schur eliminator
    
    The schur eliminator treats rows with e blocks and row with
    no e blocks separately. The template specialization logic only
    applies to the rows with e blocks.
    
    So, in cases where the rows with e-blocks have a fixed size f-block
    but the rows without e-blocks have f-blocks of varying sizes,
    DetectStructure will return a static f-block size, but we need to be
    careful that we do not blindly use that static f-block size everywhere.
    
    This patch fixes a bug where such care was not being taken, where
    it was assumed that the static f-block size could be assumed for all
    f-block sizes.
    
    A new test is added, which triggers an exception in debug mode. In
    release mode this error does not present itself, due to a peculiarity
    of the way Eigen works.
    
    Thanks to Werner Trobin for reporting this bug.

    Fix a bug in the reordering code.
    
    When the user provides an ordering which starts at a non-zero group id,
    or has gaps in the groups, then CAMD, the algorithm used to reorder
    the program can crash or return garbage results.
    
    The solution is to map the ordering into grouping constraints, and then
    to re-number the groups to be contiguous using a call to
    MapValuesToContiguousRange. This was already done for CAMD based
    ordering for Schur type solvers, but was not done for SPARSE_NORMAL_CHOLESKY.
    
    Thanks to Bernhard Zeisl for not only reporting the bug but also

    Remove legacy dependency detection macros.
    
    - Before the new CMake buildsystem in 1.8, Ceres used non-standard
      HINTS variables for dependencies.  For backwards compatibility CMake
      macros were added to translate these legacy variables into the new
      (standard) variables.
    - As it has now been multiple releases since the legacy variables
      were used and they no longer appear in any of the documentation
      support for them has now expired.

    Fix failed if() condition expansion if gflags is not found.
    
    - If a CMake-ified version of gflags is not detected, then
      gflags_LIBRARIES is not set and the TARGET condition within a
      multiconditional if() statement prevents configuration.

    Update all CMake to lowercase function name style.
    
    - Updated to new CMake style where function names are all lowercase,
      this will be backwards compatible as CMake function names are
      case insensitive.
    - Updated using Emacs' M-x unscreamify-cmake-buffer.

    Update minimum iOS version to 7.0 for shared_ptr/unordered_map.
    
    - In order to correctly detect shared_ptr (& unordered_map)
      the iOS version must be >= 7.0 (Xcode 5.0+).  This only affects the
      SIMULATOR(64) platform builds, as the OS (device) build uses the
      latest SDK which is now likely 8.0+.

    Fix bug in gflags' <= 2.1.2 exported CMake configuration.
    
    - gflags <= 2.1.2 has a bug in its exported gflags-config.cmake:
      https://github.com/gflags/gflags/issues/110 whereby it sets
      gflags_LIBRARIES to a non-existent 'gflags' target.
    - This causes linker errors if gflags is installed in a non-standard
      location (as otherwise CMake resolves gflags to -lgflags which
      links if gflags is installed somewhere on the current path).
    - We now check for this case, and search for the correct gflags imported
      target and update gflags_LIBRARIES to reference it if found, otherwise
      proceed on to the original manual search to try to find gflags.

    - The CXX11 option has no effect on Windows, as there, any new C++11
      features are enabled by default, as such to avoid confusion we only
      present the option for non-Windows.

    A refactor of the cubic interpolation code
    
    1. Push the boundary handling logic into the underlying array
    object. This has two very significant impacts:
    
    a. The interpolation code becomes extremely simple to write
    and to test.
    
    b. The user has more flexibility in implementing how out of bounds
    values are handled. We provide one default implementation.

    Fix a typo in small_blas.h
    
    The reason this rather serious looking typo has not
    caused any problems uptil now is because NUM_ROW_B is
    computed but never actually used.
    
    Thanks to Werner Trobin for pointing this out.

    Export Ceres build directory into local CMake package registry.
    
    - Optionally use CMake's export() functionality to export the Ceres
      build directory as a package into the local CMake package registry.
    - This enables the detection & use of Ceres from CMake *without*
      requiring that Ceres be installed.

    Add ProductParameterization
    
    Often a parameter block is the Cartesian product of a number of
    manifolds. For example, a rigid transformation SE(3) = SO(3) x R^3
    In such cases, where you have the local parameterization
    of the individual manifolds available,
    ProductParameterization can be used to construct a local
    parameterization of the cartesian product.

    Cleanup FindGflags & use installed gflags CMake config if present.
    
    - Split out gflags namespace detection methods:
      check_cxx_source_compiles() & regex, into separate functions.
    - Use installed/exported gflags CMake configuration (present for
      versions >= 2.1) if available, unless user expresses a preference not
      to, or specifies search directories, in which case fall back to manual
      search for components.
    -- Prefer installed gflags CMake configurations over exported gflags
       build directories on all OSs.
    - Remove custom version of check_cxx_source_compiles() that attempted
      to force the build type of the test project.  This only worked for
      NMake on Windows, not MSVC as msbuild ignored our attempts to force
      the build type.  Now we always use the regex method on Windows if
      we cannot find an installed gflags CMake configuration which works
      even on MSVC by bypassing msbuild.
    - Add default search paths for gflags on Windows.
