?

Just making something up:

<target name="hello" directory="somewhere">
  <build>make -C somedir hello</build>
  <sources>
    <file name = "PATH/foo.cpp">
       <includedirs> ... list them all </includedirs>
       <definitions> ... list them all </definitions>
       <compile>make -C somedir foo.o</compile>
       <preprocess>make -C somedir foo.i</preprocess>
       <assemble>make -C somedir foo.s</assemble>
    </file>
  </sources>
</target>

All that information is readily available, it just needs to be written out 
into some file for the IDE.

I'm afraid I can't make it there.
