# - Try to find SQLCipher
# Once done this will define
#
#  SQLCIPHER_FOUND - system has SQLCipher
#  SQLCIPHER_INCLUDE_DIR - the SQLCipher include directory
#  SQLCIPHER_LIBRARIES - Link these to use SQLCipher
#  SQLCIPHER_DEFINITIONS - Compiler switches required for using SQLCipher
#  SQLCIPHER_VERSION - This is set to major.minor.revision (e.g. 3.4.1)
#
# Hints to find SQLCipher
#
#  Set SQLCIPHER_ROOT_DIR to the root directory of a SQLCipher installation
#
# The following variables may be set
#
#  SQLCIPHER_USE_OPENSSL - Set to ON/OFF to specify whether to search and use OpenSSL.
#                          Default is OFF.
#  SQLCIPHER_OPENSSL_USE_ZLIB - Set to ON/OFF to specify whether to search and use Zlib in OpenSSL
#                               Default is OFF.
