# 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

/// \class sf::Ftp
/// \ingroup network
///
/// sf::Ftp is a very simple FTP client that allows you
/// to communicate with a FTP server. The FTP protocol allows
/// you to manipulate a remote file system (list files,
/// upload, download, create, remove, ...).
///
/// Using the FTP client consists of 4 parts:
/// \li Connecting to the FTP server
/// \li Logging in (either as a registered user or anonymously)
/// \li Sending commands to the server
/// \li Disconnecting (this part can be done implicitly by the destructor)
///
/// Every command returns a FTP response, which contains the
/// status code as well as a message from the server. Some
/// commands such as getWorkingDirectory() and getDirectoryListing()
/// return additional data, and use a class derived from
/// sf::Ftp::Response to provide this data. The most often used
/// commands are directly provided as member functions, but it is
/// also possible to use specific commands with the sendCommand() function.
///
/// Note that response statuses >= 1000 are not part of the FTP standard,
/// they are generated by SFML when an internal error occurs.
///
/// All commands, especially upload and download, may take some
/// time to complete. This is important to know if you don't want
/// to block your application while the server is completing
/// the task.
///
/// Usage example:
/// \code
/// // Create a new FTP client
/// sf::Ftp ftp;
///
/// // Connect to the server
/// sf::Ftp::Response response = ftp.connect("ftp://ftp.myserver.com");
/// if (response.isOk())
/// std::cout << "Connected" << std::endl;
///
/// // Log in
/// response = ftp.login("laurent", "dF6Zm89D");
/// if (response.isOk())
/// std::cout << "Logged in" << std::endl;
///
/// // Print the working directory
/// sf::Ftp::DirectoryResponse directory = ftp.getWorkingDirectory();
/// if (directory.isOk())
/// std::cout << "Working directory: " << directory.getDirectory() << std::endl;
///
/// // Create a new directory
/// response = ftp.createDirectory("files");
/// if (response.isOk())
/// std::cout << "Created new directory" << std::endl;
///
/// // Upload a file to this new directory
/// response = ftp.upload("local-path/file.txt", "files", sf::Ftp::Ascii);
/// if (response.isOk())
/// std::cout << "File uploaded" << std::endl;
///
/// // Send specific commands (here: FEAT to list supported FTP features)
/// response = ftp.sendCommand("FEAT");
/// if (response.isOk())
/// std::cout << "Feature list:\n" << response.getMessage() << std::endl;
///
/// // Disconnect from the server (optional)
/// ftp.disconnect();
/// \endcode

/// \class sf::Packet
/// \ingroup network
///
/// Packets provide a safe and easy way to serialize data,
/// in order to send it over the network using sockets
/// (sf::TcpSocket, sf::UdpSocket).
///
/// Packets solve 2 fundamental problems that arise when
/// transferring data over the network:
/// \li data is interpreted correctly according to the endianness
/// \li the bounds of the packet are preserved (one send == one receive)
///
/// The sf::Packet class provides both input and output modes.
/// It is designed to follow the behavior of standard C++ streams,
/// using operators >> and << to extract and insert data.
///
/// It is recommended to use only fixed-size types (like sf::Int32, etc.),
/// to avoid possible differences between the sender and the receiver.
/// Indeed, the native C++ types may have different sizes on two platforms
/// and your data may be corrupted if that happens.
///
/// Usage example:
/// \code
/// sf::Uint32 x = 24;
/// std::string s = "hello";
/// double d = 5.89;
///
/// // Group the variables to send into a packet
/// sf::Packet packet;
/// packet << x << s << d;
///
/// // Send it over the network (socket is a valid sf::TcpSocket)
/// socket.send(packet);
///
/// -----------------------------------------------------------------
///
/// // Receive the packet at the other end
/// sf::Packet packet;
/// socket.receive(packet);
///
/// // Extract the variables contained in the packet
/// sf::Uint32 x;
/// std::string s;
/// double d;
/// if (packet >> x >> s >> d)
/// {
/// // Data extracted successfully...
/// }
/// \endcode
///
/// Packets have built-in operator >> and << overloads for
/// standard types:
/// \li bool
/// \li fixed-size integer types (sf::Int8/16/32, sf::Uint8/16/32)
/// \li floating point numbers (float, double)
/// \li string types (char*, wchar_t*, std::string, std::wstring, sf::String)
///
/// Like standard streams, it is also possible to define your own
/// overloads of operators >> and << in order to handle your
/// custom types.
///
/// \code
/// struct MyStruct
/// {
/// float number;
/// sf::Int8 integer;
/// std::string str;
/// };
///
/// sf::Packet& operator <<(sf::Packet& packet, const MyStruct& m)
/// {
/// return packet << m.number << m.integer << m.str;
/// }
///
/// sf::Packet& operator >>(sf::Packet& packet, MyStruct& m)
/// {
/// return packet >> m.number >> m.integer >> m.str;
/// }
/// \endcode
///
/// Packets also provide an extra feature that allows to apply
/// custom transformations to the data before it is sent,
/// and after it is received. This is typically used to
/// handle automatic compression or encryption of the data.
/// This is achieved by inheriting from sf::Packet, and overriding
/// the onSend and onReceive functions.
///
/// Here is an example:
/// \code
/// class ZipPacket : public sf::Packet
/// {
/// virtual const void* onSend(std::size_t& size)
/// {
/// const void* srcData = getData();
/// std::size_t srcSize = getDataSize();
///
/// return MySuperZipFunction(srcData, srcSize, &size);
/// }
///
/// virtual void onReceive(const void* data, std::size_t size)
/// {
/// std::size_t dstSize;
/// const void* dstData = MySuperUnzipFunction(data, size, &dstSize);
///
/// append(dstData, dstSize);
/// }
/// };
///
/// // Use like regular packets:
/// ZipPacket packet;
/// packet << x << s << d;
/// ...
/// \endcode
///
/// \see sf::TcpSocket, sf::UdpSocket

///
/// Socket selectors provide a way to wait until some data is
/// available on a set of sockets, instead of just one. This
/// is convenient when you have multiple sockets that may
/// possibly receive data, but you don't know which one will
/// be ready first. In particular, it avoids to use a thread
/// for each socket; with selectors, a single thread can handle
/// all the sockets.
///
/// All types of sockets can be used in a selector:
/// \li sf::TcpListener
/// \li sf::TcpSocket
/// \li sf::UdpSocket
///
/// A selector doesn't store its own copies of the sockets
/// (socket classes are not copyable anyway), it simply keeps
/// a reference to the original sockets that you pass to the
/// "add" function. Therefore, you can't use the selector as a
/// socket container, you must store them outside and make sure
/// that they are alive as long as they are used in the selector.
///
/// Using a selector is simple:
/// \li populate the selector with all the sockets that you want to observe
/// \li make it wait until there is data available on any of the sockets
/// \li test each socket to find out which ones are ready
///
/// Usage example:
/// \code
/// // Create a socket to listen to new connections
/// sf::TcpListener listener;
/// listener.listen(55001);
///
/// // Create a list to store the future clients
/// std::list<sf::TcpSocket*> clients;
///
/// // Create a selector
/// sf::SocketSelector selector;
///
/// // Add the listener to the selector
/// selector.add(listener);
///
/// // Endless loop that waits for new connections
/// while (running)
/// {
/// // Make the selector wait for data on any socket
/// if (selector.wait())
/// {
/// // Test the listener
/// if (selector.isReady(listener))
/// {
/// // The listener is ready: there is a pending connection
/// sf::TcpSocket* client = new sf::TcpSocket;
/// if (listener.accept(*client) == sf::Socket::Done)
/// {
/// // Add the new client to the clients list
/// clients.push_back(client);
///
/// // Add the new client to the selector so that we will
/// // be notified when he sends something
/// selector.add(*client);
/// }
/// else
/// {
/// // Error, we won't get a new connection, delete the socket
/// delete client;
/// }
/// }

/// {
/// // The listener socket is not ready, test all other sockets (the clients)

/// \class sf::UdpSocket
/// \ingroup network
///
/// A UDP socket is a connectionless socket. Instead of
/// connecting once to a remote host, like TCP sockets,
/// it can send to and receive from any host at any time.
///
/// It is a datagram protocol: bounded blocks of data (datagrams)
/// are transfered over the network rather than a continuous
/// stream of data (TCP). Therefore, one call to send will always
/// match one call to receive (if the datagram is not lost),
/// with the same data that was sent.
///
/// The UDP protocol is lightweight but unreliable. Unreliable
/// means that datagrams may be duplicated, be lost or
/// arrive reordered. However, if a datagram arrives, its
/// data is guaranteed to be valid.
///
/// UDP is generally used for real-time communication
/// (audio or video streaming, real-time games, etc.) where
/// speed is crucial and lost data doesn't matter much.
///
/// Sending and receiving data can use either the low-level
/// or the high-level functions. The low-level functions
/// process a raw sequence of bytes, whereas the high-level
/// interface uses packets (see sf::Packet), which are easier
/// to use and provide more safety regarding the data that is
/// exchanged. You can look at the sf::Packet class to get
/// more details about how they work.
///
/// It is important to note that UdpSocket is unable to send
/// datagrams bigger than MaxDatagramSize. In this case, it
/// returns an error and doesn't send anything. This applies
/// to both raw data and packets. Indeed, even packets are
/// unable to split and recompose data, due to the unreliability
/// of the protocol (dropped, mixed or duplicated datagrams may
/// lead to a big mess when trying to recompose a packet).
///
/// If the socket is bound to a port, it is automatically
/// unbound from it when the socket is destroyed. However,
/// you can unbind the socket explicitly with the Unbind
/// function if necessary, to stop receiving messages or
/// make the port available for other sockets.
///
/// Usage example:
/// \code
/// // ----- The client -----
///
/// // Create a socket and bind it to the port 55001
/// sf::UdpSocket socket;
/// socket.bind(55001);
///
/// // Send a message to 192.168.1.50 on port 55002
/// std::string message = "Hi, I am " + sf::IpAddress::getLocalAddress().toString();

/// \class sf::Mutex
/// \ingroup system
///
/// Mutex stands for "MUTual EXclusion". A mutex is a
/// synchronization object, used when multiple threads are involved.
///
/// When you want to protect a part of the code from being accessed
/// simultaneously by multiple threads, you typically use a
/// mutex. When a thread is locked by a mutex, any other thread
/// trying to lock it will be blocked until the mutex is released
/// by the thread that locked it. This way, you can allow only
/// one thread at a time to access a critical region of your code.
///
/// Usage example:
/// \code
/// Database database; // this is a critical resource that needs some protection
/// sf::Mutex mutex;
///
/// void thread1()
/// {
/// mutex.lock(); // this call will block the thread if the mutex is already locked by thread2
/// database.write(...);
/// mutex.unlock(); // if thread2 was waiting, it will now be unblocked
/// }
///
/// void thread2()
/// {
/// mutex.lock(); // this call will block the thread if the mutex is already locked by thread1
/// database.write(...);
/// mutex.unlock(); // if thread1 was waiting, it will now be unblocked
/// }
/// \endcode
///
/// Be very careful with mutexes. A bad usage can lead to bad problems,
/// like deadlocks (two threads are waiting for each other and the
/// application is globally stuck).
///
/// To make the usage of mutexes more robust, particularly in
/// environments where exceptions can be thrown, you should
/// use the helper class sf::Lock to lock/unlock mutexes.
///
/// SFML mutexes are recursive, which means that you can lock
/// a mutex multiple times in the same thread without creating
/// a deadlock. In this case, the first call to lock() behaves
/// as usual, and the following ones have no effect.
/// However, you must call unlock() exactly as many times as you
/// called lock(). If you don't, the mutex won't be released.
///
/// \see sf::Lock

/// \ingroup system
///
/// sf::String is a utility string class defined mainly for
/// convenience. It is a Unicode string (implemented using
/// UTF-32), thus it can store any character in the world
/// (European, Chinese, Arabic, Hebrew, etc.).
///
/// It automatically handles conversions from/to ANSI and
/// wide strings, so that you can work with standard string
/// classes and still be compatible with functions taking a
/// sf::String.
///
/// \code
/// sf::String s;
///
/// std::string s1 = s; // automatically converted to ANSI string
/// std::wstring s2 = s; // automatically converted to wide string
/// s = "hello"; // automatically converted from ANSI string
/// s = L"hello"; // automatically converted from wide string
/// s += 'a'; // automatically converted from ANSI string
/// s += L'a'; // automatically converted from wide string
/// \endcode
///
/// Conversions involving ANSI strings use the default user locale. However
/// it is possible to use a custom locale if necessary:
/// \code
/// std::locale locale;
/// sf::String s;
/// ...
/// std::string s1 = s.toAnsiString(locale);
/// s = sf::String("hello", locale);
/// \endcode
///
/// sf::String defines the most important functions of the
/// standard std::string class: removing, random access, iterating,
/// appending, comparing, etc. However it is a simple class
/// provided for convenience, and you may have to consider using
/// a more optimized class if your program requires complex string
/// handling. The automatic conversion functions will then take
/// care of converting your string to sf::String whenever SFML
/// requires it.
///
/// Please note that SFML also defines a low-level, generic
/// interface for Unicode handling, see the sf::Utf classes.

/// Threads provide a way to run multiple parts of the code

///
/// To use a sf::Thread, you construct it directly with the

/// sf::Thread has multiple template constructors, which means
/// that you can use several types of entry points:
/// \li non-member functions with no argument
/// \li non-member functions with one argument of any type
/// \li functors with no argument (this one is particularly useful for compatibility with boost/std::%bind)
/// \li functors with one argument of any type
/// \li member functions from any class with no argument
///
/// The function argument, if any, is copied in the sf::Thread
/// instance, as well as the functor (if the corresponding
/// constructor is used). Class instances, however, are passed
/// by pointer so you must make sure that the object won't be
/// destroyed while the thread is still using it.
///
/// The thread ends when its function is terminated. If the
/// owner sf::Thread instance is destroyed before the
/// thread is finished, the destructor will wait (see wait())
///
/// Usage examples:
/// \code
/// // example 1: non member function with one argument
///
/// void threadFunc(int argument)
/// {
/// ...
/// }
///
/// sf::Thread thread(&threadFunc, 5);
/// thread.launch(); // start the thread (internally calls threadFunc(5))

/// class Task

/// public:
/// void run()

/// void operator()()
/// {
/// ...
/// }
/// };
///
/// sf::Thread thread(Task());
/// thread.launch(); // start the thread (internally calls operator() on the Task instance)
/// \endcode
///
/// Creating parallel threads of execution can be dangerous:
/// all threads inside the same process share the same memory space,
/// which means that you may end up accessing the same variable
/// from multiple threads at the same time. To prevent this
/// kind of situations, you can use mutexes (see sf::Mutex).

/// sf::Time encapsulates a time value in a flexible way.

/// seconds, milliseconds or microseconds. It also works the
/// other way round: you can read a time value as either
/// a number of seconds, milliseconds or microseconds.
///
/// By using such a flexible interface, the API doesn't
/// impose any fixed type or resolution for time values,
/// and let the user choose its own favorite representation.
///
/// Time values support the usual mathematical operations:
/// you can add or subtract two times, multiply or divide
/// a time by a number, compare two times, etc.
///
/// Since they represent a time span and not an absolute time
/// value, times can also be negative.
///
/// Usage example:
/// \code
/// sf::Time t1 = sf::seconds(0.1f);
/// Int32 milli = t1.asMilliseconds(); // 100
///
/// sf::Time t2 = sf::milliseconds(30);
/// Int64 micro = t2.asMicroseconds(); // 30000
///
/// sf::Time t3 = sf::microseconds(-800000);
/// float sec = t3.asSeconds(); // -0.8
/// \endcode
///
/// \code
/// void update(sf::Time elapsed)
/// {
/// position += speed * elapsed.asSeconds();
/// }
///
/// update(sf::milliseconds(100));
