# 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.
