cmake script

[stevengj]

It would be nice to include a cmake script (a CMakeLists.txt file) to make life easier for Windows users. Since utf8proc is so simple, we can easily maintain both this and a Makefile.

I'll do this. Should also turn on AppVeyor while we're at it. Are we targetting a 1.2.0 release some point soon, where we would want to get this in?

[stevengj]

I'd like to do a 1.2.0 release soon after #2 is resolved (since that will break ABI compatibility, though the API will still be backwards compatible).

(PS. Don't bother trying to reproduce the data regeneration scripts in cmake. Since we run those so rarely, it's reasonable to run them only on Unices. Just make a minimal CMakeLists that builds libutf8proc from utf8proc.c)

[tkelman]

Yeah, I don't suspect it to be more than 20 lines, really.

We will want to disallow in-tree builds from cmake though, to avoid overwriting the existing makefiles.
