Source port identification
You can identify what engine your mod is running in using ACSUtils.
How it works
The detection function first checks for presence of GetPlayerAccountName, which is a Zandronum-exclusive function. It returns a string (usually an empty string) if it exists, while unimplemented ACS functions return 0. If the function is present, the port is assumed to be Zandronum.
If the port is not Zandronum, the detection module attempts to spawn an actor of type DynamicLight, which is present in GZDoom, but not in ZDoom. If the actor spawns successfully, the port is assumed to be GZDoom.
If both these checks fail, the port is assumed to be ZDoom.
To avoid rerunning these checks every time you call one of the below functions, they are only run the first time any of the functions is called and the result is stored into a map variable. Subsequent function calls simply read the map variable.
