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 +if (SFML_STATIC_LIBRARIES) + add_definitions(-DSFML_STATIC) +endif () + +# define the list of search paths for headers and libraries +set(FIND_SFML_PATHS + ${SFML_ROOT} + $ENV{SFML_ROOT} + ~/Library/Frameworks + /Library/Frameworks + /usr/local + /usr + /sw + /opt/local + /opt/csw + /opt) + +# find the SFML include directory +find_path(SFML_INCLUDE_DIR SFML/Config.hpp + PATH_SUFFIXES include + PATHS ${FIND_SFML_PATHS}) + +# check the version number +set(SFML_VERSION_OK TRUE) +if (SFML_FIND_VERSION AND SFML_INCLUDE_DIR) + #
