> Status update on the cmake conversion:

It looks like cmake cannot do several things we need for building midas.

- it looks like cmake does not support bare object files as 1st class build targets.

We build at least two bare object files: mfe.o and mana.o for use by frontends and analyzers (and I am about
to add one more for the manalyzer). They all contain main() functions and cannot be in libmidas.a.

Stefan & co managed to kludge cmake to build mfe.o but so far I have been unable to figure out how to tell cmake
to actually use it for linking. Replacing "mfe" for -llibmfe in target_include_libraries() with "mfe.o" yields -llibmfe.o, clearly
they do not support linking to bare library object files.

So to avoid fighting cmake, libmfe.a and libmana.a are here to stay.

- it looks like cmake does not like building variant executables and object files, i.e. "with ROOT" and "without ROOT".

I need to set "-DHAVE_ROOT" for building "with ROOT" and unset it via remove_definitions() for building "without ROOT",
but remove_definitions() and add_definitions() do not work on a per-target basis, instead they operate
per-directory and per-project.

In midas, we build mlogger without ROOT (to avoid tangling it with the ROOT RPATH and ROOT shared libraries),
but if ROOT is present, we build rmlogger "with ROOT support". Same for the analyzer (mana.o and rmana.o).

For now we have this:
- mana.o is built with ROOT if ROOT is detected
- rmana.o is not built
- rmlogger is not built (not clear why)

K.O.
