I'd like to change the entire Makefile. Instead of listing the object files, I'd 
like to list the source files.

We'd have:

SOURCES = file1.c file2.c file3.c file4.cpp file5.cpp qt-ui/file6.cpp

With the sources list, we can use the preprocessor's -MG mode to create the 
list of dependencies. That way, we'll find whether the C++ source #includes any 
moc or uic output, which will then trigger the creation of such file. I need to 
study how to make that work, since it will require make to run in two passes 
(as when the Makefile updates).

The one remaining thing is grepping a list of headers for Q_OBJECT macros. So 
I'd like to list headers too, at least the ones with the macro.
