# Locate the SFML library

# This module defines the following variables:
# - For each module XXX (SYSTEM, WINDOW, GRAPHICS, NETWORK, AUDIO, MAIN):
# - SFML_XXX_LIBRARY_DEBUG, the name of the debug library of the xxx module (set to SFML_XXX_LIBRARY_RELEASE is no debug version is found)
# - SFML_XXX_LIBRARY_RELEASE, the name of the release library of the xxx module (set to SFML_XXX_LIBRARY_DEBUG is no release version is found)
# - SFML_XXX_LIBRARY, the name of the library to link to for the xxx module (includes both debug and optimized names if necessary)
# - SFML_XXX_FOUND, true if either the debug or release library of the xxx module is found
# - SFML_LIBRARIES, the list of all libraries corresponding to the required modules
# - SFML_FOUND, true if all the required modules are found
# - SFML_INCLUDE_DIR, the path where SFML headers are located (the directory containing the SFML/Config.hpp file)
#
# By default, the dynamic libraries of SFML will be found. To find the static ones instead,
# you must set the SFML_STATIC_LIBRARIES variable to TRUE before calling find_package(SFML ...).
