Because rocksdb can only be compiled into a static library in vcpkg. The rocksdb dependent library is not specified in osgearth, So the error happened.
I added RocksDB.patch to fix this problem.
VS2017PATCH has expired，Because osgearth has merged this patch, So I deleted it.
By the way, I will upgrade osgearth from 2.10.1 to 2.10.2.
