[CMake] CMake + Gradle for Android

[Jom O'Fisher]

Yeah, we'd like to support any CMake more recent than 3.7.0 (which is the
first version to support server mode). So your fork would need to be based
on a somewhat recent CMake. We probably wouldn't support a path directly in
build.gradle since that is typically a source controlled artifact. We'd let
you set a file path in local.properties and/or specify a CMake version
number in build.gradle where we'd search for it in some well-known
locations.
