# Locate SDL2_image library
|
||
|
|
# This module defines
|
||
|
|
# SDL2_IMAGE_LIBRARY, the name of the library to link against
|
||
|
|
# SDL2_IMAGE_FOUND, if false, do not try to link to SDL2_image
|
||
|
|
# SDL2_IMAGE_INCLUDE_DIR, where to find SDL_image.h
|
||
|
|
#
|
||
|
|
# Additional Note: If you see an empty SDL2_IMAGE_LIBRARY_TEMP in your configuration
|
||
|
|
# and no SDL2_IMAGE_LIBRARY, it means CMake did not find your SDL2_Image library
|
||
|
|
# (SDL2_image.dll, libsdl2_image.so, SDL2_image.framework, etc).
|
||
|
|
# Set SDL2_IMAGE_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_IMAGE_LIBRARY
|
||
|
|
# variable, but when these values are unset, SDL2_IMAGE_LIBRARY does not get created.
|
||
|
|
#
|
||
|
|
# $SDL2 is an environment variable that would
|
||
|
|
# correspond to the ./configure --prefix=$SDL2
|
||
|
|
# 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" SDL2 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_IMAGE_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" SDL2 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).
|
||
|
|
#
|
||
|
|
# Ported by Johnny Patterson. This is a literal port for SDL2 of the FindSDL.cmake
|
||
|
|
# module with the minor edit of changing "SDL" to "SDL2" where necessary. This
|
||
|
|
# was not created for redistribution, and exists temporarily pending official
|
||
|
|
# SDL2 CMake modules.
|
||
|
|
#
|
||
|
|
# Note that on windows this will only search for the 32bit libraries, to search
|
||
|
|
# for 64bit change x86/i686-w64 to x64/x86_64-w64
