Meant to help me make open source libraries with for iPhone. Only works with systems that use the "./configure && make && make install" approach.

make_iphone_libs.sh

#!/bin/sh
# Runs `./configure && make && make install' with variables set to help build libraries for iOS devices more easily.
# Hopefully, this will work as-is, but some notes...
# TODO: At least attempt to find correct directories without just failing with weird error messages
#  > $DEVROOT _will_ have to change according to Xcode installation directory.
#  > $CC or $CXX will probably change whenever a new compiler version is installed
#  > $IOS_BASE_SDK or $IOS_DEPLOY_TGT may be changed to fit developer's needs as well as future Xcode layout changes (e.g. dropping support for older iOS versions)
#  > Currently, a library for the simulator isn't being made (but should be _really_ easy to add with the existing script)

IOS_BASE_SDK="5.0"
IOS_DEPLOY_TGT="4.2"
