[Tile-serving] [osm2pgsql] Add cmake build scripts and appveyor.yml (#460)

[alex85k]

Commented
```
include(${CMAKE_CURRENT_LIST_DIR}/FindPackageHandleStandardArgs.cmake)
```
in upstream FindLua.cmake . Is it OK?

Also pre-created build folder with .gitignore and build.sh to simplify build. Is it needed?
