To find the static ones instead, +# you must set the SFML_STATIC_LIBRARIES variable to TRUE before calling find_package(SFML ...). +# You don't need to deal with SFML's dependencies when linking your targets against SFML libraries, +# they will all be configured automatically, even if you use SFML static libraries. +# example: +# set(SFML_STATIC_LIBRARIES TRUE) +# find_package(SFML 2 COMPONENTS network system) +# +# On macOS by default CMake will search for frameworks. If you want to use static libraries and have installed +# both SFML frameworks and SFML static libraries, your must set CMAKE_FIND_FRAMEWORK to "NEVER" or "LAST" +# in addition to setting SFML_STATIC_LIBRARIES to TRUE. Otherwise CMake will check the frameworks bundle config and +# fail after finding out that it does not provide static libraries. Please refer to CMake documentation for more details. +# +# Additionally, 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_DIR CMake variable +# to tell CMake where SFML's config file is located (PREFIX/lib/cmake/SFML for a library-based installation, +# and PREFIX/SFML.framework/Resources/CMake on macOS for a framework-based installation). +# +# Output +# ------ +# +# This script defines the following variables: +# - For each specified module XXX (system, window, graphics, network, audio, main): +# - SFML_XXX_FOUND: true if either the debug or release library of the xxx module is found +# - SFML_FOUND: true if all the required modules are found +# +# And the following targets: +# - For each specified module XXX (system, window, graphics, network, audio, main): +# - sfml-XXX +# The SFML targets are the same for both Debug and Release build configurations and will automatically provide +# correct settings based on your currently active build configuration.
