A Classic Fairytale: Harden all missions against missing campaign variables in team file and assume default values This assumes the worst case in which the team file is missing all campaign variables except Progress. This has been successfully tested with all 10 missions and still generates a logical storyline. By default, the game assumes: - The cyborg's offer in mission 2 was refused - The traitor in mission 5 was killed As a consequence, missions 8 and 10 use the princessScene cut scene.

# - Locate SDL2_image library
# This module defines:
#  SDL2_IMAGE_LIBRARIES, the name of the library to link against
#  SDL2_IMAGE_INCLUDE_DIRS, where to find the headers
#  SDL2_IMAGE_FOUND, if false, do not try to link against
#  SDL2_IMAGE_VERSION_STRING - human-readable string containing the version of SDL2_image
#
# For backward compatiblity the following variables are also set:
#  SDL2IMAGE_LIBRARY (same value as SDL2_IMAGE_LIBRARIES)
#  SDL2IMAGE_INCLUDE_DIR (same value as SDL2_IMAGE_INCLUDE_DIRS)
#  SDL2IMAGE_FOUND (same value as SDL2_IMAGE_FOUND)
#
# $SDL2DIR is an environment variable that would
# correspond to the ./configure --prefix=$SDL2DIR
# used in building SDL2.
#
# Created by Eric Wing. This was influenced by the FindSDL2.cmake
# module, but with modifications to recognize OS X frameworks and
# additional Unix paths (FreeBSD, etc).
