# This module defines |
|
||||
# SDL2_LIBRARY, the name of the library to link against |
|
||||
# SDL2_FOUND, if false, do not try to link to SDL2 |
|
||||
# SDL2_INCLUDE_DIR, where to find SDL.h |
|
||||
# SDL2_DLL_DIR, where to find SDL2.dll if it exists |
|
||||
# |
|
||||
# This module responds to the the flag: |
|
||||
# SDL2_BUILDING_LIBRARY |
|
||||
# If this is defined, then no SDL2main 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_LIBRARY variable. |
|
||||
# |
|
||||
# Don't forget to include SDLmain.h and SDLmain.m your project for the |
|
||||
# OS X framework based version. (Other versions link to -lSDL2main which |
|
||||
# this module will try to find on your behalf.) Also for OS X, this |
|
||||
# module will automatically add the -framework Cocoa on your behalf. |
|
||||
# |
|
||||
# |
|
||||
# Additional Note: If you see an empty SDL2_LIBRARY_TEMP in your configuration |
|
||||
# and no SDL2_LIBRARY, it means CMake did not find your SDL2 library |
|
||||
# (SDL2.dll, libsdl2.so, SDL2.framework, etc). |
|
||||
# Set SDL2_LIBRARY_TEMP to point to your SDL2 library, and configure again. |
|
||||
# Similarly, if you see an empty SDL2MAIN_LIBRARY, you should set this value |
|
||||
# as appropriate. These values are used to generate the final SDL2_LIBRARY |
|
||||
# variable, but when these values are unset, SDL2_LIBRARY does not get created. |
|
||||
# |
|
||||
# |
|
||||
# $SDL2DIR is an environment variable that would |
|
||||
# correspond to the ./configure --prefix=$SDL2DIR |
|
||||
# used in building SDL2. |
|
||||
# l.e.galup 9-20-02 |
|
||||
# |
|
||||
# Modified by Eric Wing. |
|
||||
# Added code to assist with automated building by using environmental variables |
|
||||
# and providing a more controlled/consistent search behavior. |
|
||||
# Added new modifications to recognize OS X frameworks and |
|
||||
# additional Unix paths (FreeBSD, etc). |
|
||||
# Also corrected the header search path to follow "proper" SDL guidelines. |
|
||||
# Added a search for SDL2main which is needed by some platforms. |
|
||||
# Added a search for threads which is needed by some platforms. |
|
||||
# Added needed compile switches for MinGW. |
|
||||
# |
|
||||
# On OSX, this will prefer the Framework version (if found) over others. |
|
||||
# People will have to manually change the cache values of |
|
||||
# SDL2_LIBRARY to override this selection or set the CMake environment |
|
||||
# CMAKE_INCLUDE_PATH to modify the search paths. |
|
||||
# |
|
||||
# Note that the header path has changed from SDL2/SDL.h to just SDL.h |
|
||||
# This needed to change because "proper" SDL convention |
|
||||
# is #include "SDL.h", not <SDL2/SDL.h>. This is done for portability |
|
||||
# reasons because not all systems place things in SDL2/ (see FreeBSD). |
