For now, this only covers linux on the two architectures we have testing support for. However, it serves as a good sanity check and can be expanded in the future.

This change also removes policy settings that are now already set to
`NEW` by default. There are still two remaining policies that were
introduced in CMake > 3.10, so I left those, and documented the CMake
version they were introduced in so we know when we can later remove them
(when our min version advances beyond that).
The min CMake version supported by Protobuf is documented here:

These will still use MSVC as the compiler, but will no longer generate Visual Studio projects for the builds. Visual Studio is particularly bad at parallelizing builds, and is hostile to ccache.
This change also tweaks the ccache setup to prevent unbounded the growth observed in our github caches. Windows builds have had debug symbols stripped to reduce ccache size by a factor of 2x, and ccache maximum have been tweaked so that we persist fewer older builds.
Before this change, each CMake build took 12 minutes on every run (plus some constant overhead from staleness/gcloud), even with caching or on large multi-core runners. No amount of caching or parallelization made any noticeable difference above noise. With this change, we see the following improvements:
- 12 minutes to build from scratch on normal runners (unchanged)
- 4 minutes on 32-core runners from scratch
- 1 minute with optimal caches available on normal runners.
- 30 seconds on 32-core runners with optimal caches

This uses ccache + github caching to substantially decrease the time it takes to run CMake builds. Due to Bazel caching, these are some of our slowest tests, causing one of the biggest presubmit bottlenecks

This deletes our old branches of internal Abseil code in favor of their newly open-sourced library. Notably, this removes the ability to turn CHECK crashes into exceptions.

This leaves the decision of which C++ version to use up to our users. We still have a static_assert in port_def.inc that will prevent pre-C++14 usage.

Fix misdetection of libatomic with strict compiler flags
With strict flags and -Werror, the detection for libatomic breaks, causing it to be included in places where it is not needed. And on macOS, this leads to a link error when libatomic cannot be found.
Closes#10899

This cl hit an issue during the shared library cmake build from ODR violations, leading to mismatched absl hash seeds. The problem was pre-existing but didn't manifest until now, and can be traced to the fact that in shared library builds we linked Abseil statically. All of the cmake changes here remove the underlying ODR violation.

This change enables projects that consume protobuf via
`FetchContent_MakeAvailable()` to set the C++ version to be used. This is
necessary, as linking code compiled for different C++ standards is asking for
trouble (and will simply not work in some cases).
Check that any version that might be set in `CMAKE_CXX_STANDARD` is new
enough (C++14 or later). On Cygwin, check if any `-std=gnu++XX` has
already been set. In all cases, default to C++14.
* Proof of concept for Abseil dependency
* Adding most common Abseil libraries
* Fixing shared library breakages
* Switching to quotes over angled brackets
* Disable install target by default
* Fixing abseil to LTS commit
* Upgrade to latest Abseil LTS
* Turning install back on by default, removing unnecessary export statements
* Add note to future self
* Fixing unsafe globals
* Upgrade third_party/googletest submodule to current main branch
We can finally do this upgrade now that we have dropped our autotools
build. Googletest recommends living at head, so let's go straight to the
most recent commit on main. For some reason the googletest archive is
not present in the Bazel build mirror, so I removed that entry and just
left the GitHub download link in our WORKSPACE file.
Googletest now requires C++14, so I updated all the C++11 flags I could
find to C++14 instead. I added a .bazelrc file to add -std=c++14 for all
our Bazel builds.
* Delete the empty //src/google/protobuf:protobuf_test target
* Avoid building C++ unit tests in aarch64 jobs for Python and Ruby

* Support older versions of CMake.
VERSION_GREATER_EQUAL is supported by CMake >=3.7:
https://cmake.org/cmake/help/latest/command/if.html#version-greater-equal
target_link_options() is supported by CMake >=3.13:
https://cmake.org/cmake/help/latest/command/target_link_options.html
* Use PROTOBUF_USE_DLLS and LIBPROTOC_EXPORTS for libprotoc.so shared library
Similar change for libprotobuf.so and libprotobuf-lite.so was made
in commit 5a0887fc65.
* Make value of PROTOC_EXPORT dependent on LIBPROTOC_EXPORTS instead of LIBPROTOBUF_EXPORTS
This was probably intention, and LIBPROTOC_EXPORTS is also used above
in _MSC_VER branch.
Convenience feature: enable users to test via the familiar `ctest` command rather than making the `check` target.
They would be able to use the familiar CMake pattern:
```
cmake -S source/protobuf -B build/protobuf ...
cmake --build build/protobuf
ctest --test-dir build/protobuf
cmake --install build/protobuf
```
This is a follow-up to 9f447fc9d3da93da29b8301f1a8ca57b1ea812d7
when using CMake >= 3.15, we use CMAKE_MSVC_RUNTIME_LIBRARY
to reproduce the /MT vs /MD when protobuf_MSVC_STATIC_RUNTIME
is TRUE or FALSE
MultiThreaded is for /MT
MultiThreadedDebug is for /MTd
MultiThreadedDLL is for /MD
MultiThreadedDebugDLL is for /MDd
This is based on @haberman's changes in #8257. Now that we're using
std::mutex we no longer need to check whether pthreads are available, so
this commit removes references to HAVE_PTHREAD. I left the autotools
build alone, though, since we are likely to drop support for it soon
anyway.
The `VERSION_GREATER_EQUAL` operator was introduced in CMake 3.7.0
(released in 2016). Use the long form of the check by splitting the
operation into two comparisons to support the older CMake.
When using a new enough CMake (3.15+) prefer to use the
`MSVC_RUNTIME_LIBRARY` property on targets to select the runtime library
variant. This property is automatically set to the value specified by
`CMAKE_MSVC_RUNTIME_LIBRARY`. This property requires that the CMake
Policy 91 is set to new (see CMP0091).
