That isn’t that simple. https://www.sqlite.org/download.html has separate libraries for 32-bit and 64-bit windows, and you have to write code to figure out what DLL to load (see http://system.data.sqlite.org/index.html/doc/trunk/www/faq.w...)

Nowadays, you mostly can ignore x86, but I guess you still hit similar problems if you want your code to run on Windows for ARM, .NET core on Linux, etc.
