Sameer Agarwal 0a53aa9054 Take abseil as a dependency
1. Add abseil-cpp as a submodule. We are tracking the latest LTS
release, which is lts_2024_01_16.
2. Replace glog/gflags with absl::log and absl::flags.
3. Remove miniglog
4. Also take a whack at making the bazel build work with
   abseil-cpp and gtest.

There are a number of TODOs in this CL that still need to be resolved.

Sergiu Deitsch 91773746be Simplify instantiation of cost functions and their functors
If arguments are passed to a cost function that can be used to construct
the functor, the latter will be instantiated by the cost function using
std::make_unique to ensure exception safety. This not only avoids static
analysis warnings caused by calling new but also spelling the cost
functor type name multiple times.

Also expand deduction guides for instantiating
Dynamic(Auto|Numeric)DiffCostFunction from std::unique_ptr enabled
constructor overloads.

Finally, make CostFunction default move constructible and assignable but
only through derived classes. This in turn allows derived classes to be
movable without relying on custom implementations of corresponding
operators.

Sergiu Deitsch 09ec4997fa Cleanup examples
Remove logic invoked based on obsolete variable definitions. Use new
(explicit) target_link_libraries syntax to link binaries against
dependencies. Do not rely on prior knowledge about the compiler for
specifying flags and system libraries but instead directly test their
presence to be more robust.

Nikolaus Demmel 7b8f675bfd fix formatting for (non-generated) internal source files
- Change formatting standard to Cpp11. Main difference is not having
  the space between two closing >> for nested templates. We don't
  choose c++14, because older versions of clang-format (version 9
  and earlier) don't know this value yet, and it doesn't make a
  difference in the formatting.
- Apply clang-format to all (non generated) internal source files.
- Manually fix some code sections (clang-format on/off) and c-strings
- Exclude some embedded external files with very different formatting
  (gtest/gmock)
- Add script to format all source files

Nikolaus Demmel 7b6b2491cc fix formatting for examples
This is mostly just applying the existing clang format config, except:
- Use NOLINT on overlong comment lines.
- Wrap some sections in 'clang-format off' / 'clang format on'.
- Manually split or join some multi-line strings.

Alex Stewart aa1abbc578 Replace use of GFLAGS_LIBRARIES with export gflags target
- As our minimum required version of gflags (2.2) exports itself as
  a CMake package and this is the case for the default 18.04 package
  we can use the gflags target directly.
- Replaces forced use of CONFIG in find_package(gflags) with a check
  that the gflags imported target exists to avoid ambiguity with
  libgflags if installed in a default location.  This permits users to
  override the gflags detection should they so choose, provided that
  they do so via an imported target.
- Also removes some previously removed legacy GLAGS_ vars from the
  installation docs.

Alex Stewart b70687fcc8 Add namespace qualified Ceres::ceres CMake target
- This reflects modern CMake style, and also provides a measure of
  protection against missing find_package() imports in downstream
  clients resulting in linker errors when 'ceres' matches the compiled
  library and not the imported target.
- The original 'ceres' target remains, as a local imported interface
  target created by CeresConfig for backwards compatibility.

NeroBurner a548766d14 Use glfags target
Update the usage of Google Flags (gflags) library the same way Glog
updated it [1]. This pushes the minimum required gflags version to
v2.2.0.

Remove the ceres specific define of CERES_GFLAGS_NAMESPACE and directly
use GFLAGS_NAMESPACE defined in gflags/gflags_declare.h [2].

In CeresConfig.cmake the hard coded paths for gflags are ommited.
Instead we rely on the gflagsConfig file to get closer to a relocatable
CeresConfig.cmake.
Furthermore use the find_dependency() [4] cmake function specifically
created for cmake-config files.

This change builds upon the explicit PUBLIC/PRIVATE link change [3].

Sergey Sharybin 54ba6c27b5 Fix missing declaration warnings in Ceres code
This commit includes the following:

- Changes to CMake to make it safer to see which compiler flags are supported,
  so this way we do not need to worry about version checks in CMake.

- Unix platforms (which includes both Linux and Apple as far as i can tell)
  will now enable -Wmissing-declarations warning for the whole Ceres.

- Changes in all sources to solve missing declaration warning. In most cases
  it was either matter of using static qualifier or moving functions to an
  anonymous namespace.

  In one case the function got removed, since it seems to be unused.

  Additionally, in slam examples there was a non-inlined function implementation
  in a header, which is a direct way to cause linking errors if other .cc file
  will include that helper header.

- All third party sources (which is currently only gmock) has this extra
  paranoid warning disabled.

This warning is important in the following cases:

- Detect helper functions which are not needed anymore.
- Avoid unnoticed pollution of namespace.
- Avoid bad level calls.
- Avoid missing updates in header files after changes in implementation file.
- Helps integrating Ceres into software where paranoid warnings are important.
