WorldTileModel.h not found when trying to generate LODs

When including the WorldBrowser/Private/Tiles/WorldTileCollectionModel.h header to use the FWorldTileCollectionModel::GenerateLODLevels method, I get this error
WorldTileCollectionModel.h(6): [C1083] Cannot open include file: 'Tiles/WorldTileModel.h': No such file or directory
So then when trying to include this file, I get another error
WorldTileModel.h(8): [C1083] Cannot open include file: 'LevelModel.h': No such file or directory
And including this header doesn’t change anything I keep getting this error.

These headers are in the module WorldBrowser which is my Build.cs, and I use other methods from it in my file, so I don’t think the problem comes from the module references.

Any ideas how to fix this ?
