-- Predefine platform and compiler macros for the PythonQt wrapper generator.
-- The generator uses a bundled copy of simplecpp instead of the system compiler
-- to preprocess Qt headers.  On FreeBSD with libc++ this fails because the
-- bundled preprocessor does not define the usual Clang/FreeBSD macros that
-- libc++ and system headers require.  Predefine the missing macros so the
-- generator can successfully parse Qt 6 headers and produce wrappers.
--
-- Upstream builds the generator and runs it on platforms where the system
-- compiler predefines these values implicitly; FreeBSD needs them explicitly.
