Fix #382 #74 disable SQLITECPP_USE_STACK_PROTECTION when running on MinGW

As I understand 0xc0000139 could be referring to a DLL not found (https://www.reddit.com/r/learnprogramming/comments/9o28ax/how_to_fix_this_error_during_startup_program/) I use lucasg/Dependencies when I had issues related to DLL´s(as Dependency Walker does not work in Windows 11) but I don´t know if it works in mingw, If I have some spare time will try to replicate it on a VM with mingw

edit: just checked it and indeed if there is a dll missing on windows it returns 0xC0000139

Thanks, you gave me the right idea! All I needed then was search for more info (missing DLLs from the PATH) and experiment with how to add mingw bin/ dir to the path!
