# FindMySQL
# ---------
#
# Try to locate the mysql client library.
#
# By default, pkg-config is used, if available.
# If pkg-config is not available or if you want to disable it, set the ``MySQL_ROOT`` variable.
# The following variables can be set to control the behavior of this find module.
#
# ``MySQL_ROOT``
#     The root directory of the mysql client library's installation.
# ``MySQL_INCLUDE_DIR``
#     The directory containing the include files of the mysql client library.
#     If not set, the directory is detected within ``MySQL_ROOT`` using find_path.
# ``MySQL_LIBRARY_DIR``
#     The directory containing the binaries of the mysql client library.
#     This is used to detect ``MySQL_LIBRARY`` and passed as HINT to find_library.
# ``MySQL_LIBRARY``
#     The file path to the mysql client library.
# ``MySQL_LIBRARY_DEBUG``
#     The file path to the mysql client library for the DEBUG configuration.
#
# If the mysql client library is found, this will define the following variables:
#
# ``MySQL_FOUND``
#     True if the mysql library is available
# ``MySQL_INCLUDE_DIRS``
#     The mysql include directories
# ``MySQL_LIBRARIES``
#     The mysql libraries for linking
#
# If ``MySQL_FOUND`` is TRUE, it will also define the following
# imported target:
#
# ``MySQL::MySQL``
#     The mysql client library
