where i can find old versions of SDK's supported on m1's architecture

We have a program which was created on old MacOS SDK, now I am trying to build it in my new MacBook with M1 chip. I have found SDKs, that are not supported on M1 architecture. Is there any way to solve this problem?

I'm not sure it's this library's role to document the nuances of SDK compatibility however I recently was able to leverage stdc++ using 10.9 SDK on Apple M1 by explicitly including the following path to my project MacOSX10.9.sdk/usr/include/c++/4.2.1, which I was unable to find documentation for anywhere.
