Of course Andrew is right. Someone has to spend some time to write the
EPICS specific rules. But in case of CMake most of this work has been
done already (see the links in my first mail).

Building for multiple architectures comes for free with CMake as it
supports out-of-source builds (actually they are default).
Cross-building is possible as well. It's supported with many different
tool chains. Of course you can add your own tool chain as well.

Creating dependency files should be an easy exercise but I think you
don't need them with CMake (it takes care of things like that
automatically). With Make it's difficult to write build rules that work
for parallel builds (e.g. make -j 4) with CMake it's difficult to write
rules that do not.

So I would still recommend using CMake for apps/libs that build on top
of EPICS base.

Regards,

Martin
