1# Locate SDL2 library
2# This module defines
3# SDL2_LIBRARY, the name of the library to link against
4# SDL2_FOUND, if false, do not try to link to SDL2
5# SDL2_INCLUDE_DIR, where to find SDL.h
6#
7# This module responds to the the flag:
8# SDL2_BUILDING_LIBRARY
9# If this is defined, then no SDL2main will be linked in because
10# only applications need main().
11# Otherwise, it is assumed you are building an application and this
12# module will attempt to locate and set the the proper link flags
13# as part of the returned SDL2_LIBRARY variable.
14#
15# Don't forget to include SDLmain.h and SDLmain.m your project for the
16# OS X framework based version. (Other versions link to -lSDL2main which
17# this module will try to find on your behalf.) Also for OS X, this
18# module will automatically add the -framework Cocoa on your behalf.
19#
20#
21# Additional Note: If you see an empty SDL2_LIBRARY_TEMP in your configuration
22# and no SDL2_LIBRARY, it means CMake did not find your SDL2 library
23# (SDL2.dll, libsdl2.so, SDL2.framework, etc).
24# Set SDL2_LIBRARY_TEMP to point to your SDL2 library, and configure again.
25# Similarly, if you see an empty SDL2MAIN_LIBRARY, you should set this value
26# as appropriate. These values are used to generate the final SDL2_LIBRARY
27# variable, but when these values are unset, SDL2_LIBRARY does not get created.
28#
29#
30# $SDL2DIR is an environment variable that would
31# correspond to the ./configure --prefix=$SDL2DIR
32# used in building SDL2.
33# l.e.galup 9-20-02
34#
35# Modified by Eric Wing.
36# Added code to assist with automated building by using environmental variables
37# and providing a more controlled/consistent search behavior.
38# Added new modifications to recognize OS X frameworks and
39# additional Unix paths (FreeBSD, etc).
40# Also corrected the header search path to follow "proper" SDL guidelines.
41# Added a search for SDL2main which is needed by some platforms.
42# Added a search for threads which is needed by some platforms.
43# Added needed compile switches for MinGW.
44#
45# On OSX, this will prefer the Framework version (if found) over others.
46# People will have to manually change the cache values of
47# SDL2_LIBRARY to override this selection or set the CMake environment
48# CMAKE_INCLUDE_PATH to modify the search paths.
49#
50# Note that the header path has changed from SDL2/SDL.h to just SDL.h
51# This needed to change because "proper" SDL convention
52# is #include "SDL.h", not <SDL2/SDL.h>. This is done for portability
53# reasons because not all systems place things in SDL2/ (see FreeBSD).
