- Move CMake superbuild files
- Drop use of `CMakeLists.txt.in` configure files
- Allow overriding dependency directories. For now, this should only be
used by GitHub workflows. Will be expanded on later, possibly renaming
the variables.
This change is one in a series to make it easier to consume/customize
Sandboxed API in downstream projects.
Drive-by:
- Update `.gitignore` to ignore clangd's `.cache` directory

Bazel readily enforces header visiblity for each target, CMake is more lenient.

This allows resource-constrained environments to benefit from the
space savings of dynamic linking. This is not meant to be used in
the general case.

- Extract dependent types directly from the Clang AST and re-serialize
back into compilable code
- Collect types and emit diagnostics
- Format generated code

Practically all current compilers fully support C++17 by now, with the exception of `filesystem` (which we won't use).

This fixes some CMake-3.12+-isms, like `list(JOIN ...)` and setting link
properties on OBJECT libraries.

This change moves away from a classical superbuild which downloads and builds
at build time. Instead, we now follow a "Fetch Content" workflow (available as
FetchContent in CMake 3.11+) and download dependencies at config time.
Rationale: Superbuild projects have the disadvantage that projects cannot
directly access their individual declared targets. This is not a problem with
regular libraries, as those are usually/supposed to be installed. With
Sandboxed API, this is not desirable, as it has dependencies like Abseil and
glog, which are almost always consumed by including their source tree using
add_subdirectory().
Fixes#10 and makes external embedding easier.

* Move add_sapi_library() into a build defs file
* Override protobuf_generate_cpp() instead of naming it sapi_protobuf_generate_cpp()
* Factor out inclusion/find_package() calls of external dependencies

* Implement add_sapi_library() similar to the Bazel rule
* Fix SuperBuild so that glog properly depends on gflags (needed for --logtostderr)
* Raise minimum required version of CMake to 3.10 (Ubuntu 18.04 LTS)
* Update sum sandbox policy to allow to get IDs and PIDs

This change adds CMake targets for the actual Sandboxed API library. On its
own, this is not very useful, as there is no CMake equivalent to the
sapi_library() rule, yet. This will be worked on next.

This change also tries to make the build more idempotent wrt to embedding projects.

Since the interface generator is invoked via a Bazel macro, it will be
expanded in the embedding context of the project using SAPI, so package access
needs to go through the full workspace root @com_google_sandboxed_api.
This change also modifies the CMakeLists.txt accordingly, as the "external"
subdirectory is no longer needed/wanted.
