  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).
