-# Locate SDL2 library
|
| 10 | |
-# This module defines
|
| 11 | |
-# SDL2_LIBRARY, the name of the library to link against
|
| 12 | |
-# SDL2_FOUND, if false, do not try to link to SDL
|
| 13 | |
-# SDL2_INCLUDE_DIR, where to find SDL.h
|
| 14 | |
-#
|
| 15 | |
-# This module responds to the the flag:
|
| 16 | |
-# SDL2_BUILDING_LIBRARY
|
| 17 | |
-# If this is defined, then no SDL_main will be linked in because
|
| 18 | |
-# only applications need main().
|
| 19 | |
-# Otherwise, it is assumed you are building an application and this
|
| 20 | |
-# module will attempt to locate and set the the proper link flags
|
| 21 | |
-# as part of the returned SDL_LIBRARY variable.
|
| 22 | |
-#
|
| 23 | |
-# Don't forget to include SDLmain.h and SDLmain.m your project for the
|
| 24 | |
-# OS X framework based version. (Other versions link to -lSDL2main which
|
| 25 | |
-# this module will try to find on your behalf.) Also for OS X, this
|
| 26 | |
-# module will automatically add the -framework Cocoa on your behalf.
|
| 27 | |
-#
|
| 28 | |
-#
|
| 29 | |
-# Additional Note: If you see an empty SDL2_LIBRARY_TEMP in your configuration
|
| 30 | |
-# and no SDL2_LIBRARY, it means CMake did not find your SDL library
|
| 31 | |
-# (SDL.dll, libsdl.so, SDL.framework, etc).
|
| 32 | |
-# Set SDL_LIBRARY_TEMP to point to your SDL library, and configure again.
|
| 33 | |
-# Similarly, if you see an empty SDLMAIN_LIBRARY, you should set this value
|
| 34 | |
-# as appropriate. These values are used to generate the final SDL_LIBRARY
|
| 35 | |
-# variable, but when these values are unset, SDL_LIBRARY does not get created.
|
| 36 | |
-#
|
| 37 | |
-#
|
| 38 | |
-# $SDL2DIR is an environment variable that would
|
| 39 | |
-# correspond to the ./configure --prefix=$SDL2DIR
|
| 40 | |
-# used in building SDL.
|
| 41 | |
-# l.e.galup 9-20-02
|
| 42 | |
-#
|
| 43 | |
-# Modified by Eric Wing.
|
| 44 | |
-# Added code to assist with automated building by using environmental variables
|
| 45 | |
-# and providing a more controlled/consistent search behavior.
|
| 46 | |
-# Added new modifications to recognize OS X frameworks and
|
| 47 | |
-# additional Unix paths (FreeBSD, etc).
|
| 48 | |
-# Also corrected the header search path to follow "proper" SDL guidelines.
|
| 49 | |
-# Added a search for SDLmain which is needed by some platforms.
|
| 50 | |
-# Added a search for threads which is needed by some platforms.
|
| 51 | |
-# Added needed compile switches for MinGW.
|
| 52 | |
-#
|
| 53 | |
-# On OSX, this will prefer the Framework version (if found) over others.
|
| 54 | |
-# People will have to manually change the cache values of
|
| 55 | |
-# SDL_LIBRARY to override this selection or set the CMake environment
|
| 56 | |
-# CMAKE_INCLUDE_PATH to modify the search paths.
|
| 57 | |
-#
|
| 58 | |
-# Note that the header path has changed from SDL/SDL.h to just SDL.h
|
| 59 | |
-# This needed to change because "proper" SDL convention
|
| 60 | |
-# is #include "SDL.h", not <SDL/SDL.h>. This is done for portability
|
| 61 | |
-# reasons because not all systems place things in SDL/ (see FreeBSD).
