### CMake Configuration for Protobuf

Source: https://github.com/cartavis/carta-protobuf/blob/dev/CMakeLists.txt

Configures CMake to find Protobuf, specify proto file locations, and generate C++ code. Use this to integrate Protobuf-generated code into your C++ project.

```cmake
SET(Protobuf_IMPORT_DIRS shared stream control request .)
FIND_PACKAGE(Protobuf REQUIRED)
INCLUDE_DIRECTORIES(${PROTOBUF_INCLUDE_DIR})
file(GLOB PROTO_FILES
        "shared/*.proto"
        "control/*.proto"
        "request/*.proto"
        "stream/*.proto"
        )
PROTOBUF_GENERATE_CPP(PROTO_SRC PROTO_HEADER ${PROTO_FILES})
ADD_LIBRARY(carta-protobuf ${PROTO_HEADER} ${PROTO_SRC})
```

### Encode Tile Coordinates in JavaScript

Source: https://github.com/cartavis/carta-protobuf/blob/dev/docs/src/data_cube_navigation.md

A JavaScript function to encode tile layer, x, and y coordinates into a single 32-bit integer. This is used for efficient storage and transmission of tile information.

```javascript
(x, y, layer) => (layer << 24) | (y << 12) | x;
```
