I will try.
This is a recurrent issue with CMake (I'm not blaming anyone here, but
I faced similar issues many times): it evolves (which is great !), but
it is quite common to encounter some kind of regressions even with
"patch level" releases. As the exact version of cmake varies from one
machine to another, it is really hard to write CMakeFiles.txt and keep
them in sync to keep them working while CMake evolves. At least with
cross-compilation projects.

I can't remember the reason for the "FORCE_C_COMPILER", so it may not
been required or even recommended anymore. If I can get rid of it, I
will.

Ok. I don't know why I added '4', maybe it's a left over syntax from
early CMake versions, or I copied a wrong sample file somewhere. It
has been there for 2 or 3 years though ;-).

Thanks a lot for your help,
