Building unicorn from source on Alpine fails with /home/venom/mtkclient/unicorn/qemu/util/oslib-posix.c:33:10: fatal error: linux/mman.h: No such file or directory

I'm trying to build unicorn from source for mtkclient on Alpine because I get an error from it and multiple other packages.
The error I'm getting from building from source is:

/home/venom/mtkclient/unicorn/qemu/util/oslib-posix.c:33:10: fatal error: linux/mman.h: No such file or directory
   33 | #include <linux/mman.h>
      |          ^~~~~~~~~~~~~~
compilation terminated.

If you want the errors I get from using pip3 install unicorn, I will be glad to give them.

Ok, I just ran pip3 install unicorn again and realized that I get the same errors.

I guess apk add py3-(pip3 package that couldn't be installed) works. Might not be as stable, but I will try it.
DOES NOT WORK! (I thought it was going to for a moment)
