-!!! warning
-    Installing Nominatim through CMake is now deprecated. The infrastructure

-
-The code must be built in a separate directory. Create the directory and

-Nominatim uses cmake and make for building. Assuming that you have created the

-cmake ../Nominatim

-sudo make install

-Nominatim installs itself into `/usr/local` per default. To choose a different
