[oe] [meta-oe][PATCH] rocksdb: make resulting cmake config relocatable

[Pascal Bach]

RocksDB is still using CMake 2.8 and thus does not make use of importet targets.
This leads to hardcoded paths to the build directory in the resulting packaged files.

The workaround for the issue is to bypass CMakes detection and let the linker deal with finding the right library.

This is necessary until RocksDB moves to a more modern CMake.
It's also applied in the Poco recipe right now.
