Add a way to specify custom build settings

[mstfy]

Is there a way to add custom build settings to scipio. It would be handy to specify an xcconfig file during to compilation of spm packages. With this way ve can enable and disable certain thing without touching the scipio's code. For example new mergable libraries.

Hi!

ScipioKit provides extraFlags and extraBuildParameters.
https://giginet.github.io/Scipio/documentation/scipio/build-pipeline#Pass-Custom-Build-Flags

You can pass custom build settings for all packages or the specific package.

But we don't provide this feature for the CLI version of scipio. Please make your wrapper script.
It's said in the documentation. However, our documentation is not enough yet. If you have any question, feel free to ask here

Tried it but it crashes with the error that says invalid package. I created simple package just contains Alamofire as dependency. My xcode version is xcode 15.

Sorry, supporting Xcode 15 was maintained in another branch.

I supported both Xcode 15 and 14.3 on a current main. Could you try this?
