[Windows] How to setup the environment variables GZDoom uses to searchfor IWADs?

Post by HenKonen »

See title. I haven't found an answer

Just so you know, everything is working - GZdoom g4.14.0 found the IWADs from my Steam Copies of Doom and others, but as a fan of knowing how things work I'd like to inspect what exactly are the default paths stored in environment variables $DOOMWADDIR, $HOME and $PROGDIR and if there are ways to reconfigure these variables on windows.

The environment variables are found under [IWADSearch.Directories] in the gzdoom.ini file generated by GZDoom upon launch. But I've yet to find where these variables are configured and whether it is possible to have them point to another path.

They are dynamically generated from hard code.

For finding Steam/GOG games it tries to locate your database and then search games based off of that.
