Build script for building SDL2 and extensions for iOS, tvOS and macOS

get_sdl.sh

#!/bin/bash
#
# usage: Make executable and type ./get_sdl.sh
#
# Note - Use -showBuildSettings such as:
# xcodebuild -configuration Release HEADER_SEARCH_PATHS="../../SDL/include/ ./Frameworks/FreeType.framework/Headers/" -target "Static Library" -arch x86_64 -sdk macosx -showBuildSettings
# to list all build settings...
#
# Note - Had to update the HEADER_SEARCH_PATHS and MACOSX_DEPLOYMENT_TARGET for
# a couple of libraries for the macOS versions. The HEADER_SEARCH_PATHS were set to look
# for a .framework for SDL.h etc. and the MACOSX_DEPLOYMENT_TARGET is set to 10.5
# but produces an error saying 10.6 is required.
#
# Ideas taken from: https://gist.github.com/i8degrees/74f977f41082c89b33fe
# and https://github.com/ThirdPartyNinjas/sdl_ios/blob/master/sdl_ios.sh
