Right and thats doable with CMake and KDevelop, including 4.2 as far as
I can see from the source. The way things work in KDevelop is that it
builds whatever is currently selected in the project tree or if there's
something in the list under "Project Selection" in the Projects toolview
on the left it builds that. Hence if you add only a .cpp file from your
project tree into the project selection and then do Project->Build
Selection (or hit the build button) it'll build just that single .cpp
file by running 

make foo.o 

in the builddirectory (if the file is foo.cpp). As was already said,
there seems to be a bug in some cases but that should produce an error
message and not build anything at all.
