[CMake] cross compiling

[Jesse Corrington]

I definitely want to go the first route of adding support to generate mmp
and inf files. We are using the carbide plugin for eclipse which loads those
files, so it's needed. I don't really know much more about the tool chain
stuff, I just had read a previous mailing list email where someone was
talking about symbian and pointed in the direction of the cross compiling
article on the cmake wiki.  I am doing this work at my current job where we
have software that needs to be built on Symbian v2, v2.1, v3, windows mobile
5 and 6, the new linux java mobile platform, windows desktop, and other
platforms in the future. Currently we have a mess of MSVC project files,
makefiles, mmp/inf, etc, so it really needs to change so they are all
generated from a common script. It is only for our internal builds, not so
that others can build our software on whatever platform they want.
