# 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})
# define the SFML_STATIC macro if static build was chosen
