If the system has CLEW installed (which is detected by recently added FindCLEW routines) then OpenSubduv would be compiled against this library. It makes binaries and libraries more portable across the systems, so it's possible to run the same binary on systems with and without OpenCL SDK installed. The most annoying part of the change is updating examples to load OpenCL libraries, but ideally code around controllers and interface creation is to be de-duplicated anyway. Based on the pull request #303 from Martijn Berger
