* Use early exit in objc_framework CMakeLists.txt * Clean up objc_framework CMakeLists.txt * Use `version` consistently * Use `firebase_ios_version` for the repo-level version * Remove INCLUDE directories that are no longer needed * Sort dependencies * Simplify Example/App/CMakeLists.txt * Add `OBJC_FLAGS` directly, avoiding a separate `sources` variable. * Add resources directly * Rename test host app to firebase_firestore_example_app * Add a firebase_ios prefix to functions and variables This reduces the chance of collision with other projects. * Simplify compiler_setup Now that compiler_setup.cmake no longer has side-effects, fold compiler_id.cmake and archive_options.cmake into it and move the include of compiler_setup up to the top of the main build. * Add support for building for iOS * Make building benchmarks optional * Disable protoc-based source generators when cross-compiling * Make downloading googletest optional * Add DISABLE_STRICT_WARNINGS mode to cc_rules This makes it possible to build non-Firestore components in the CMake build to a lower standard than that to which we hold ourselves without sacrificing the utility of the various build rules that we have.
