Unity builds?

[gvl2023]

I'm excited about this new feature. However cmake docs for CMAKE_EXPORT_COMPILE_COMMANDS says:

This option currently does not work well in combination with the [UNITY_BUILD](https://cmake.org/cmake/help/latest/prop_tgt/UNITY_BUILD.html#prop_tgt:UNITY_BUILD) target property or the [CMAKE_UNITY_BUILD](https://cmake.org/cmake/help/latest/variable/CMAKE_UNITY_BUILD.html#variable:CMAKE_UNITY_BUILD) variable.

We are using cmake unity builds and they are hard to impossible to disable... Am I going to hit a wall with LSP and unity builds because of the above? Don't want to spend time experimenting if it's known to not work. I managed to get the CDT classic indexer to (mostly) work via the build output parser provider, so curious if this is a case of "if it works don't touch it".

Not necessarily. There are more possibilities to generate a compile_commands.json. Check this llvm page. Please check also this clangd page for further details on how to tell clangd to determine the compile settings.
