+# 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})
