Lowering depends on Semantics and the Parser, and Semantics depends on Parser, have you tried using REUSE_FROM https://cmake.org/cmake/help/latest/command/target_precompile_headers.html#reusing-precompile-headers so that lowering can reuse the precompiled headers too?

Just curious, I am not familiar with that cmake feature at all.
