First of all, great job on the library!

I could not get the library to compile under 4.4.0-53-generic Ubuntu 16.04.1 LTS x86_64 , because it failed at :PathfinderJava:linkPathfinderjavaX64SharedLibrary Ran ./gradlew build here is the output:

Any ideas?

Fixed it like this: https://github.com/newjanson/Pathfinder/commit/ecf7317604557bd2053c35d79c082b54b155d6b8 I'm very unexperienced when it comes to gradle, so feel free to let me know if there is a better way of doing this. Will also make a PR.
