Subject: [PATCH] Associate the required include directory with the benchmark
 library (#393)

Using target_include_directories CMake will implicitly add the the
necessary include paths to targets which link against the benchmark
library. This is useful when the benchmark repo is included as a
subdirectory in another CMake build.
