For context:

Without this change we would see lots of repeated warnings during build:

Explicit modules is enabled but the compiler was not recognized; disable explicit modules with
CLANG_ENABLE_EXPLICIT_MODULES=NO, or use
C_COMPILER_LAUNCHER with CLANG_ENABLE_EXPLICIT_MODULES_WITH_COMPILER_LAUNCHER=YES if using a compatible launcher

config.build_settings["CLANG_ENABLE_EXPLICIT_MODULES_WITH_COMPILER_LAUNCHER"] = "YES"
end
