Title: Update documentation to use working configure_file command signature from COPY_ONLY to documented COPYONLY

I believe the configure_file signature requires COPYONLY (no underscore). http://www.cmake.org/cmake/help/v3.0/command/configure_file.html

Surprised I did not get an error before the change, which would have been helpful in debugging.
