# This will define the following variables::

#   MYSQL_FOUND           - True if the system has the libraries
#   MYSQL_INCLUDE_DIRS    - where to find the headers
#   MYSQL_LIBRARIES       - where to find the libraries
#   MYSQL_DEFINITIONS     - compile definitons

# Hints:
# Set ``MYSQL_ROOT_DIR`` to the root directory of an installation.
