Why not.  Clean patches are of course accepted and dirty ones
will at least be discussed.  :-)

I don't think anyone has tried to cross-compile Hatari since
we switched to CMake, so detecting the right features from
the host's build system might be a problem.


Here's CMake documentatation on cross-building with CMake:
	http://www.cmake.org/Wiki/CMake_Cross_Compiling

At least on Debian Stable, the CMake platform files are in:
	/usr/share/cmake-<version>/Modules/Platform/

You might start by constructing your own Platform file
from the "Generic" and "GNU" .cmake files in there.


Potentially problematic CMake command constructs in Hatari sources
you can find with:
------
for cmd in try_ find_ add_custom_; do
	echo "COMMAND: $cmd";
	echo "-----------";
	grep $cmd $(find -iname '*cmake*');
done
------

It can look at start a bit scary, but most of the custom commands
it shows are for creating manpages and cleaning up build results
which I would assume to work fine also in cross-compiling.


As to the built binary, I don't expect any particular issues.
Besides the few library dependencies, Hatari uses standard C & Unix
stuff which should work fine also on MiNT as long as SDL works fine.
