              # This is necessary because moc's (built-in) preprocessor evaluates conditions
              # and expands macros and thus the set of defined macros can affect its
              # output. For example, signals and/or slots can be defined conditionally.
              #
              # Not all compilers have a mode that produces such a macro list. GCC, Clang,
              # and the Intel compiler do, but MSVC (for one) does not.
              #
              # The upstream build does not generate this header unless the compiler
              # supports such a mode (that is, moc gets no macro definitions at all). The
              # only exception is MSVC in which case Qt5 uses qmake to produce the required
              # output (by passing /Bx<path-to-qmake> to cl.exe, specifying an alternative
              # preprocessor executable), and Qt6 (via CMake) does nothing except for adding
              # the WIN32 macro to moc's definitions. We emulate the Qt6 behavior here for
              # now.
              #
              # Note also that this approach is not limited to the Qt libraries themselves:
              # applications may have preprocessor directives that affect the moc output and
