# 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 ...)

/// \class sf::Vector4
|

/// \ingroup system
|

///
|
||||
/// sf::Vector4 is a simple class that defines a mathematical
|
||||
/// vector with two coordinates (x and y). It can be used to
|
||||
/// represent anything that has two dimensions: a size, a point,
|
||||
/// a velocity, etc.
|
||||
///
|
||||
/// The template parameter T is the type of the coordinates. It
|
||||
/// can be any type that supports arithmetic operations (+, -, /, *)
|
||||
/// and comparisons (==, !=), for example int or float.
|
||||
///
|
||||
/// You generally don't have to care about the templated form (sf::Vector4<T>),
|
||||
/// the most common specializations have special typedefs:
|
||||
/// \li sf::Vector4<float> is sf::Vector4f
|
||||
/// \li sf::Vector4<int> is sf::Vector4i
|
||||
/// \li sf::Vector4<unsigned int> is sf::Vector4u
|
||||
///
|
||||
/// The sf::Vector4 class has a small and simple interface, its x and y members
|
||||
/// can be accessed directly (there are no accessors like setX(), getX()) and it
|
||||
/// contains no mathematical function like dot product, cross product, length, etc.
|
||||
///
|
||||
/// Usage example:
|
||||
/// \code
|
||||
/// sf::Vector4f v1(16.5f, 24.f);
|
||||
/// v1.x = 18.2f;
|
||||
/// float y = v1.y;
|
||||
///
|
||||
/// sf::Vector4f v2 = v1 * 5.f;
|
||||
/// sf::Vector4
|
||||
/// v3 = v1 + v2;
|
||||
///
|
||||
/// bool different = (v2 != v3);
|
||||
/// \endcode
|
||||
///
|
||||
/// Note: for 3-dimensional vectors, see sf::Vector3.
