MapLibre Tile support pulls in the maplibre-tile-spec submodule and needs cmake to build it, which is a lot to ask of anyone who only wants to work with Mapbox Vector Tiles. `make MLT=0` compiles with -DNO_MLT, skips the submodule and its cmake build entirely, and drops the MLT tests from `make test`. The result needs no dependencies beyond the ones MVT already needed, and can be built from a checkout with no submodules at all. Everything that touches the MLT library is behind the #ifdef, which is just the two files that were written for it. The option parsing and the tile format helpers stay compiled either way, so nothing else needs to know: --output-format=mlt reports that the build has no MLT support rather than being an unrecognized value, and a tile that is recognized as MLT reports the same instead of being misparsed as a protobuf, since the format sniffing itself doesn't need the library. CI builds and tests this configuration from a checkout without submodules, so it can't quietly stop working.
