* Require CMake 3.5.1
This is the version required by the latest versions of gRPC and Google
Benchmark. See discussion https://github.com/google/benchmark/pull/613.
Remove version check around find_package(XCTest)
Also, add a dependency on objc protos that was missing but somehow
implicitly being added before.
* Upgrade Google Benchmark to 1.5.0
* Add deployment targets for osx
* Fix bundle path to make spec tests work
On iOS, resources are directly within the bundle so the bundlePath and
the resourcePath are the same.
On macOS, resources are in a Contents/Resources subfolder so enumerating
from bundlePath causes us to look for names like
Contents/Resources/offline_spec_test, which doesn't work.
* Fix documentation warnings that show up under the macOS build
* Step one of benchmarking
* Benchmark writing to leveldb
* Comment out and style
* More comments
* Fix warnings
* Someday I will lint as good as computer
* Some light commenting and static-ing
* It seems to be working?
* Remove unused test file
* Drop commented-out deps
* Revert string quoting in pbxproj file
* Drop reference to deleted file
* Move podspec, fix import
* Lots of C++ style changes
* Style
