# Find MySQL.
#
# This module prefers the MariaDB implementation of MySQL (it works better, especially on Windows). It will
# only look for standard MySQL if MariaDB is not found.
#
# Set this variable to any additional path you want the module to search:
# MySQL_DIR
#
# Imported targets defined by this module:
# MySQL::mysql - shared library if available, or static if that's all there is
# MySQL::mysql_shared - shared library
# MySQL::mysql_static - static library
#
# Informational variables:
# MySQL_FOUND - MySQL (or all requested components of MySQL) was found.
# MySQL_VERSION - the version of MySQL that was found
# MySQL_IS_MARIADB - TRUE if the MySQL that was found is MariaDB
#
