# Try to find RocksDB headers and library.

#

# Usage of this module as follows:

#

#     find_package(RocksDB)

#

# Variables used by this module, they can change the default behaviour and need

# to be set before calling find_package:

#

#  ROCKSDB_ROOT_DIR          Set this variable to the root installation of

#                            RocksDB if the module has problems finding the

#                            proper installation path.

#

# Variables defined by this module:

#

#  ROCKSDB_FOUND               System has RocksDB library/headers.

#  ROCKSDB_LIBRARIES           The RocksDB library.

#  ROCKSDB_INCLUDE_DIRS        The location of RocksDB headers.

#  ROCKSDB_VERSION             The RocksDB version
