But we have a wrapper already, why do we need two of them? It seems to
me one should be enough, if we can instruct wine to load said libs
before loading the app, no?

Sorry, I have to admit: this linking, importing, etc. is all Chinese to me.
Is this ignorance of importing variables a limitation of Winelib that we
can fix (import libraries?), or is it something fundamentally unfixable?
BTW, can you please take a look here:
It seems I'm running in the same problem.
The way I understand it though is a bit different (or so it seems to me):
-- wine calls PROCESS_InitWine (first thing it does in main())
-- PROCESS_InitWine -> open_builtin_exe_file -> wine_dll_load_main_exe
-- wine_dll_load_main_exe -> dlopen_dll
So this one loads the .so, and this triggers the static initializers to
run, thus calling the statically constructed classes, right? And here
the problem happens. Why? Because the kernel & friends have not yet been
