# - Find SDL2_image library and headers
|
|
#
|
|
# Find module for SDL_image 2.0 (http://www.libsdl.org/projects/SDL_image/).
|
|
# It defines the following variables:
|
|
# SDL2_IMAGE_INCLUDE_DIRS - The location of the headers, e.g., SDL_image.h.
|
|
# SDL2_IMAGE_LIBRARIES - The libraries to link against to use SDL2_image.
|
|
# SDL2_IMAGE_FOUND - If false, do not try to use SDL2_image.
|
|
# SDL2_IMAGE_VERSION_STRING
|
|
# Human-readable string containing the version of SDL2_image.
|
|
#
|
|
# Also defined, but not for general use are:
|
|
# SDL2_IMAGE_INCLUDE_DIR - The directory that contains SDL_image.h.
|
|
# SDL2_IMAGE_LIBRARY - The location of the SDL2_image library.
