ADT/SDK and cmake - generating the toolchain/cmake config

[Jonathan Austin <jonathan.austin@arm.com>]

Hi all,

The ADT documentation walks you through building an 'app' using 
autoconf/make, and the environment setup script that is created as part 
of the SDK build contains all the necessary autofoo/environment 
variables. This is great, and I've worked through the autotools example 
happily. Thanks :)

What I can't find, though, is anything that does the equivalent for 
cmake. I'm new to cmake so could be missing something obvious, but after 
seeing the 'environment-setup-TARGET' files (the ones at 
/opt/poky/1.5.1/) I thought there might also be a cmake toolchain file 
(toolchain-TARGET.cmake, for example) or some other cmake-foo.

I can see that cmake support was merged for Eclipse/ADT, so it seems 
like cmake could be supported 'outside the IDE', but I can't quite see 
how what I ought to twiddle to do this. I found the tantalizingly named 
'cmake_do_generate_toolchain_file()' and all the other relevant stuff in 
meta/classes/cmake.bbclass, but I don't know what the 'right' way to 
propagate all that stuff into the SDK/ADT would be.

Any help with getting started would be greatly appreciated.

Thanks
Jonny
