<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">I have had this same problem. We have a few methods of setting the location of the proj.db file. When we call from C++ (or from python), there’s a function called OSRSetPROJSearchPaths that’s handy.
If you’re calling from a command line, you could try setting your environment variable just before calling your function (set “PROJ_LIB=c:\path\to\proj\”). I think there’s also a command line option to set your PROJ_LIB. You could try adding “--config PROJ_LIB
“c:\path\to\proj”” to your command line and see what that does. I haven’t personally tried it.<o:p></o:p></span></p>

<p class="MsoNormal"><span lang="EN-US" style="color:#1F497D">I haven’t had to do these things as much with the python/conda distributions of the commandline programs for whatever reason.<o:p></o:p></span></p>
