Can I have some assistance getting these upstream?

Hi @fire! Thanks for the contribution. Sorry, I didn't have time yet to look into it, but I'm interested in supporting mingw builds and help you upstream patches. Possibly we can also do some changes to CMake filesinstead of source changes in some instances.
Unfortunately, this may have to wait a bit, I'm currently pretty busy with finishing my thesis and am trying to prioritize here.

This doesn't seem to have a huge demand so I'll probably close the issue.

Let's leave it open, I think mingw support would be really nice to have.
I once had a look at the patches, but some needed rework (removing unrelated changes) that i had no time for, so I had shelved this task.

Maybe you could create individual pull requests with the relevant changes for those individual projects hosted on github (or another public repo), that would already be 90% of the way :)
