Thanks for that.

There's one last thing that is missing for kde4_automoc to be compatible with qmake,
and that would be: support for Q_OBJECT in .cpp files. This would be very very useful
for unit tests (writing one file instead of two).

Currently the only way to support that seems to be #include "moc_foo.cxx" (weird extension)
and QT4_WRAP_CPP(), but that's a bit too manual compared to kde4_automoc
(where listing all source files isn't needed).

So my request would be that moc_foo.cpp (for qmake compat) gets generated
when foo.cpp has Q_OBJECT and #includes moc_foo.cpp  -- and if this means too
much parsing it could be disabled by default and enabled by a directory-wide option,
but after all we have to load the .cpp files already for normal kde4_automoc, right?
