#  MYSQL_LIBRARIES, the libraries needed to use MySQL.
#  MYSQL_LIB_DIR, path to the MYSQL_LIBRARIES
#  MYSQL_EMBEDDED_LIBRARIES, the libraries needed to use MySQL Embedded.
#  MYSQL_EMBEDDED_LIB_DIR, path to the MYSQL_EMBEDDED_LIBRARIES
#  MYSQL_FOUND, If false, do not try to use MySQL.
#  MYSQL_EMBEDDED_FOUND, If false, do not try to use MySQL Embedded.
