# 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 (ie. 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}) #
