* Rename FIREBASE_BINARY_DIR to FIREBASE_INSTALL_DIR
Make this consistent with the outer superbuild and also make the
association with CMAKE_INSTALL_PREFIX more obvious.
* Build and test log_stdio separate from the rest of util
This is in preparation for adding a test for log_apple
* Build and test log_apple under CMake
Also add notes about how FIRLogger's debug mode can break this test
* Refactor log_apple to cut down duplicate switch statements
There's also a slight reduction in final binary size.
* Deprecate FIRAppEnvironmentUtil sharedApplication
* Remove sharedApplication private API.
This also allows us to remove an AppKit dependency.
* Disable autolink when building FirebaseCore (#606)
This prevents the dependencies of FirebaseCore's dependencies from
bleeding into its interface.
The proximate benefit of avoiding this is that FirebaseCore no longer
ends up depending on ColorSync.framework which became a top-level system
framework in 10.13. This makes it possible to build against the
resulting FirebaseCore.framework on macOS 10.12 using Xcode 9 (with the
macOS 10.13 SDK).
* Don't bother specifying a download directory to CMake ExternalProject
* Teach CMake to build pure Xcode projects as dependencies
This allows downstream code (like log_apple.mm) to consume this for
testing within the CMake build without requiring a CMake-native build
for these components.
This makes integrating these components into the cmake build essentially
free from the point of view of the consumed component.
* Get the CMake build semi-working on Linux again
Many prebuilt versions of cmake on Linux lack the ability to download
over https so use git to get googletest.
Don't attempt to build FirebaseCore on Linux; there's no xcodebuild.
Note the build is still ultimately broken because we don't yet have an
alternative to arc4random on Linux but at least this is no more broken
than it was before.
