I am using sentencepiece in a downstream application where I want to minimize the resulting closures. This commit makes changes to make sentencepiece a leaner dependency: - Split the outputs, so that the binaries/headers do not end up in the transitive closure in a library dependency. - Add the `withGPerfTools` option, which is enabled by default, to make it possible to disable the gperftools dependency. According to the sentencepiece README, this dependency gives a 10-40% performance improvement. But in many cases this is overshadowed by the neural networks that use piece identifiers as input anyway.
