-# This script locates the SFML library
-# ------------------------------------
-#
-# Usage
-# -----
-#
-# When you try to locate the SFML libraries, you must specify which modules you want to use (system, window, graphics, network, audio, main).
-# If none is given, the SFML_LIBRARIES variable will be empty and you'll end up linking to nothing.
-# example:
-#   find_package(SFML COMPONENTS graphics window system) # find the graphics, window and system modules
-#
-# You can enforce a specific version, either MAJOR.MINOR or only MAJOR.
-# If nothing is specified, the version won't be checked (i.e. any version will be accepted).
-# example:
-#   find_package(SFML COMPONENTS ...)     # no specific version required
-#   find_package(SFML 2 COMPONENTS ...)   # any 2.x version
-#   find_package(SFML 2.4 COMPONENTS ...) # version 2.4 or greater
-#
-# 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 ...).
-# Since you have to link yourself all the SFML dependencies when you link it statically, the following
-# additional variables are defined: SFML_XXX_DEPENDENCIES and SFML_DEPENDENCIES (see their detailed
-# description below).
-# In case of static linking, the SFML_STATIC macro will also be defined by this script.
-# example:
-#   set(SFML_STATIC_LIBRARIES TRUE)
-#   find_package(SFML 2 COMPONENTS network system)
-#
-# On Mac OS X if SFML_STATIC_LIBRARIES is not set to TRUE then by default CMake will search for frameworks unless
-# CMAKE_FIND_FRAMEWORK is set to "NEVER" for example. Please refer to CMake documentation for more details.
-# Moreover, keep in mind that SFML frameworks are only available as release libraries unlike dylibs which
-# are available for both release and debug modes.
-#
-# If SFML is not installed in a standard path, you can use the SFML_ROOT CMake (or environment) variable
-# to tell CMake where SFML is.
-#
-# Output
-# ------
-#
-# This script defines the following variables:
-# - For each specified 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_XXX_DEPENDENCIES:    the list of libraries the module depends on, in case of static linking
-# - 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)
-# - SFML_DEPENDENCIES: the list of libraries SFML depends on, in case of static linking
-#
-# example:
-#   find_package(SFML 2 COMPONENTS system window graphics audio REQUIRED)
-#   include_directories(${SFML_INCLUDE_DIR})
-#   add_executable(myapp ...)
-#   target_link_libraries(myapp ${SFML_LIBRARIES})
