[CMake] how to add capability to generate preprocessed and not-yet-compiled files ?

[Alexander Neundorf]

Hi,

it would be nice if it would be possible to have for each object file also a target which only preprocesses the file and one which preprocesses and compiles, but not assembles the file (so that you get the assembler code).

Is there a way to do this with macros ? 
I almost think this would have to be done in cmake itself. Probably somewhere where the object rules are created additionally for each object the same rule but with "-E" instead of "-c" would have to be created. It wouldn't be required to be executed on all, just on direct invocation:
make foo.o/pre
make foo.o/as


What do you think about this ?
Would you accept a patch ?

Bye
Alex
