Fix CMake build

[Youw]

After one of the expat updates, CMake build is no longer working.

I did a quick look at it - the issue is that expat being moved to expat/expat.

Not going to prepare a PR right now - just to keep track of things.

cb5ac6e is the responsible commit.

I think this simple change should fix it:

 set(PACKAGE_BUGREPORT "expat-bugs@libexpat.org")

@drizt (as the one user of the cmake build known to me), any chance you could verify it?

[Youw]

I've tried - it is much more complicated.
Let me share my results.

Sorry :(

As a matter of sport interest, I have a fix here: Youw@ded0c90
But I wouldn't take it as a solution - install target collects some garbage (like expat headers ans static lib).

Maybe someone, who more interested in CMake build, might improve it.

On the other hand, not entirely correct but working - is better solution, than broken.

[drizt]

I have own fix.

@drizt Please submit a PR. Thanks!

I've tried to follow up work on this, but eventually, I gave up... I ended up with using ExternalProject in CMake, it is hardcoded for x64 Release for VS 2017, as it is enough for me. Hard part was learning about nuget downloaded package. Maybe someone will find it useful
