MBTiles format

[ComradeMashkov]

I'm wondering, how can I manage MBTiles format creation with Rocky? I tried the snippet of code just like in rsimple.cpp file.

This is the code which works great (TMS):

#ifdef ROCKY_HAS_TMS
auto layer = rocky::TMSImageLayer::create();
#endif

And this is the code that doesn't work (MBTiles):

#ifdef ROCKY_HAS_MBTILES
auto layer = rocky::MBTilesImageLayer::create();
#endif

So I can build my code with TMS support, but I can't with MBTiles support, because I'm constantly getting linker erros:

What should I do to implement MBTiles loading?

My fault. There was a typo that caused MBTilesImageLayer to not be built properly.
Fixed in 75f6555.
Thanks for pointing this out!
