Installed .hpp tries to include a .cpp file about xlnt

I've been using the library in-place so I never noticed this issue. It turns out we don't need to include miniz.h until we get into implementation files since I'm using a forward declaration in zip_file.hpp. My most recent commit should fix this for you. I'll close the issue if it works.

I think that worked! I assume including miniz.h in zip_file.cpp isn't including all the code? Because miniz.c gets linked in as well, and that would include the same code twice. But it looks like miniz.h defines MINIZ_HEADER_FILE_ONLY which I assume means forward declarations only? If correct, then everything is good with your latest commit. Thanks for the fix!

That's right. It's an unusual system, but it allows the whole library to be a single file. Happy to help!
