While building a wxWidgets app for iOS, I wanted to build wxWidgets as a library, not include it as part of the application as the minimal iOS example does. The following script (based on ios-autotools) sets up the required environment and then calls the supplied configure script.
- The main changes are:
- the configure script is passed as a parameter so that it does not need to be in the same directory as the iconfigure script which keeps the source folder unchanged
- if an SDK version is passed in and the SDK for that version of the SDK does not exist then the default SDK is used with the ios-min-version set to the specified version.

echo " All additional parameters are passed to the configure script."
