You can also build a minimal version of it with a drastically reduced file
size if you want to avoid recompiling Qt now and in the future. This post

However, I'd probably make sure to build it using the appropriate version
of MSVC (depending on which version of python you are targeting), rather
than using the posted mingw version.
