Making existing extension independent of Source branch
 

I have a forked extension of LateDL I have been working on and improving.

Currently, the extension requires me to compile it against specific SDKs using the --sdks argument (ex. --sdks=l4d2,tf2).
I would like to be able to compile this extension as a "generic" extension so it can be used by any version of the Source engine regardless of game.

How would I accomplish this?

I have tried using the no-SDK AMBuilder scripts, but when I compile the extension with those scripts, I get the following error:
Something in this extension is relying on platform-specific imports, but I'm not experienced enough with making extensions to figure out what is it and if I can replace it with something that will allow generic branch compatibility.
