Found it, fixed it, it compiles now. There were some missing 'typename'
issues that had to be fixed, and I added newlines to the end of several
files. The new patch is attached.

Of course I was too lazy to test it on linux, and I _only_ tested jpeg,
but mingw is a step in the right direction :)

What, for finding the extension? You should not need filesystem for

Personaly I think there should be a separate header, and/or a macro, so
that overlaods supporting path can be used.
It would be an 'optional' dependancy.

Anyhow, the library is already not header-only, it requires libpng,
jpeg6b, zlib, and libtiff. None of these seem work perfectly on windows
/ msvc without a little bit of tweaking (#defines conflict, etc).

Can you provide some exampes, perhaps add an 'examples' folder and/or a
'tests' folder with some code that shows how the library can be used.
