# - Find SDL2 library and headers
|
|
#
|
|
# Find module for SDL 2.0 (http://www.libsdl.org/).
|
|
# It defines the following variables:
|
|
# SDL2_INCLUDE_DIRS - The location of the headers, e.g., SDL.h.
|
|
# SDL2_LIBRARIES - The libraries to link against to use SDL2.
|
|
# SDL2_FOUND - If false, do not try to use SDL2.
|
|
# SDL2_VERSION_STRING - Human-readable string containing the version of SDL2.
|
|
#
|
|
# This module responds to the the flag:
|
|
# SDL2_BUILDING_LIBRARY
|
|
# If this is defined, then no SDL2_main will be linked in because
|
|
# only applications need main().
|
|
# Otherwise, it is assumed you are building an application and this
|
|
# module will attempt to locate and set the the proper link flags
|
|
# as part of the returned SDL2_LIBRARIES variable.
|
|
#
|
|
# Also defined, but not for general use are:
|
|
# SDL2_INCLUDE_DIR - The directory that contains SDL.h.
|
|
# SDL2_LIBRARY - The location of the SDL2 library.
|
|
# SDL2MAIN_LIBRARY - The location of the SDL2main library.
|
